Detective Superintendent Lewis Basford said the baby is “at the heart of the investigation” and that concerns are rising “day by day” for the child’s wellbeing.
He said the public should be aware that the couple have made an effort to remain inconspicuous, and that their “change of disguise” as well as movement and “shielding” of the baby has made it hard to locate them.
“We know they’ve worn masks, we know they’ve changed coats at various times just within the two to three days since the Met Police have taken the inquiry and followed them,” he said.
He added that the couple have “now removed the stroller” and are “more aware and paranoid that actually the police and members of the public will be more cognisant of a baby”.

In a message to the couple, Det Supt Basford said: “Constance and Mark, your baby has spent the first month of its short life exposed to the elements when it should be safe and warm and, most importantly, seen by medics.
“After a month you must be running low on cash. Please pick up the phone and let us know, at the very least, that you are okay. We are ready to come to you and see that you and the baby get medical attention.
“We know that the baby was still alive on 8 January and finding the baby remains our top priority.”
He also appealed particularly to those who may have spent time in the countryside near Newhaven and elsewhere in Sussex, where the couple are believed to be camping.
He urged that any detail, no matter how small, was important, including if an individual gave the couple directions or saw them buying food, drink or nappies.
Ms Marten, who is from a wealthy family, has lived an isolated life with Mr Gordon, a convicted sex offender, since they met in 2016.
It is thought most of the couple’s belongings were destroyed in the blaze that affected their vehicle.
Since then, Ms Marten and Mr Gordon have taken a taxi to Liverpool, and from there to Harwich in Essex. They have also been seen in east London, before travelling to north London and then on to East Sussex.
Pictures released on 8 January showed the pair walking near Brick Lane, east London, at around 11.45pm where they dumped a pushchair.

When spotted in East Sussex, they were carrying bags containing a two-man tent, sleeping bags and pillows that they had bought from Argos.
The last known sighting of the pair was at 6.15am on 8 January, where they walked along Cantercrow Hill, East Sussex, into the fields beyond.
They were carrying a number of bags and their blue tent, although given the time that’s passed they could have moved some considerable distance.
Three people have died following a helicopter crash during a flying lesson on the Isle of Wight.
A fourth person is in hospital in a serious condition following the incident, according to Hampshire Police.
Officers were called to the scene of a “helicopter that had come down” off Shanklin Road near Ventnor at 9.24am on Monday, the force said.
A spokesman for the aircraft’s owner Northumbria Helicopters said G-OCLV – which is listed as a Robinson R44 II helicopter – was involved in the accident during a flying lesson.

Four people, including the pilot, were on board the aircraft, which departed nearby Sandown Airport at 9am, the company also said in a statement.
A critical care team, including a doctor and specialist paramedic, was also sent to the crash site, Hants and Isle of Wight Air Ambulance added, alongside fire engines and other emergency vehicles.
The Air Accidents Investigation Branch confirmed it was alerted to the incident and is sending a team to investigate. A major incident was declared but has since been stood down.
A spokesperson for Hampshire and Isle of Wight Air Ambulance said in a statement: “We have treated and airlifted one patient to the Major Trauma Centre, University Hospital Southampton. Our thoughts are with them, and everyone involved in today’s incident.”
Darren Toogood, editor and publisher at the Island Echo, told Sky News presenter Kamali Melbourne the helicopter crashed on a “significantly busy, high-speed road” between the village of Godshill and the seaside town of Shanklin.
“It was on one of the first flights of the day,” he said.
“It’s a bank holiday weekend in August on the Isle of Wight. It’s an incredibly busy area. Lots of tourists down at the moment. It appears no vehicles were involved, which is incredible, given how busy this road would have been this morning.”
A witness, Leigh Goldsmith, told the Isle of Wight County Press she saw the helicopter “spiralling” before crashing into a hedge as she drove along the road.
Ten child protection organisations have written an urgent letter to the home secretary expressing concern about the omission of child sexual abuse from the government’s violence against women and girls strategy, following a Sky News report.
Groups including the NSPCC, Barnardo’s and The Internet Watch Foundation wrote to Yvette Cooper to say that violence against women and girls (VAWG) and child sexual abuse are “inherently and deeply connected”, suggesting any “serious strategy” to address VAWG needs to focus on child sexual abuse and exploitation.
The letter comes after Sky News revealed an internal Home Office document, titled Our draft definition of VAWG, which said that child sexual abuse and exploitation is not “explicitly within the scope” of their strategy, due to be published in September.

Responding to Sky News’ original report, Poppy Eyre, who was sexually abused and raped by her grandfather when she was four, said: “VAWG is – violence against women and girls. If you take child sexual abuse out of it, where are the girls?”
The Centre of Expertise on Child Sexual Abuse, which is funded by the Home Office and a signatory to the letter, estimates 500,000 children in England and Wales are sexually abused every year.
The NSPCC “welcome” the government’s pledge to halve VAWG in a decade, but is “worried that if they are going to fulfil this commitment, the strategy absolutely has to include clear deliverable objectives to combat child sexual abuse and exploitation too”, the head of policy, Anna Edmundson, told Sky News.

She warned the government “will miss a golden opportunity” and the needs of thousands of girls will be “overlooked” if child sexual abuse and exploitation is not “at the heart of its flagship strategy”.
The government insists the VAWG programme will include action to tackle child sexual abuse, but says it also wants to create a distinctive plan to “ensure those crimes get the specialist response they demand”.
“My message to the government is that if you’re going to make child sexual abuse a separate thing, we need it now,” Poppy told Sky News.
Rape Crisis, which is one of the largest organisations providing support to women in England and Wales, shares these concerns.
It wants plans to tackle child sexual abuse to be part of the strategy, and not to sit outside it.

“If a violence against women and girls strategy doesn’t include sexual violence towards girls, then it runs the risk of being a strategy for addressing some violence towards some females, but not all,” chief executive Ciara Bergman said.
A Home Office spokesperson said the government is “working tirelessly to tackle the appalling crimes of violence against women and girls and child sexual exploitation and abuse, as part of our Safer Streets mission”.
“We are already investing in new programmes and introducing landmark laws to overhaul the policing and criminal justice response to these crimes, as well as acting on the recommendations of Baroness Casey’s review into group-based Child Sexual Exploitation, and the Independent Inquiry into Child Sexual Abuse,” they added.
Hundreds of shoplifting cases have gone unsolved every day, with the number of unsolved incidents rising by more than 40,000 over the past year.
New figures show that 289,464 cases of shoplifting were shut by police without a suspect in England and Wales in the year to March 2025, according to House of Commons library analysis.
Of all shoplifting cases, more than half (55%) were closed without a suspect identified, while fewer than one in five (18%) led to someone being charged.
The data shows the number of cases closed without a suspect has also risen significantly on the previous 12 months, with 245,337 cases shut by police forces without a suspect being identified in 2023-24, a rise of more than 40,000.
The analysis, produced for the Liberal Democrats, suggests that on average, 793 shoplifting offences went unsolved every day.
Senior Conservative politicians have told Sky News that the figures “explain why Britain feels lawless”, and are urging ministers to scrap plans to largely end the use of short prison sentences, in favour of people serving time in the community.

What else does the data show?
The data covered all police forces in England and Wales, except for Humberside, but also included the British Transport Police.
It revealed the Metropolitan Police had the worst record, with 76.9% of its 93,705 shoplifting cases being closed with nobody identified as a suspect. Just 5.9% of shoplifting incidents recorded in the capital and the wider region resulted in a charge.
While the data has shown the number of unsolved cases is on the rise, it also revealed that the total number of shoplifting offences has increased dramatically, too.

Do we send too many people to prison?
In 2023-24, 444,022 cases of shoplifting were recorded. But in 2024-25, this rose to 530,643, a record high since the practice of recording the data nationally began in 2002-03.
Overall, 2,071,156 offences of all types went unsolved in the 2024-25 year. This means, on average each day, 5,674 crimes were committed that went on to be closed without a suspect. Only 7.3% of all crimes recorded resulted in somebody being charged or summoned.

Greggs shoplifter caught
The Lib Dems have repeated their calls for police and crime commissioners – elected politicians who have authority over each police force – to be scrapped. They believe the money spent on these would be better invested in frontline policing, and that police boards, made up of local councillors and other individuals, could replace them.
Lisa Smart, the party’s home affairs spokesperson, said that the data reveals an “absolute scandal” because it shows that “thousands of innocent victims are being left without the justice they deserve” every day.
She added: “The previous Conservative government left behind a legacy of failure, but the Labour government has not been quick enough to address the unsolved crime epidemic – particularly as shoplifting spirals out of control.”

Tories: There should be a ‘zero tolerance approach’ to shoplifting
Meanwhile, the shadow home secretary pointed out that shoplifting has risen by 20% under Labour, and that ministers show “no signs of gripping it”.
Chris Philp told Sky News: “The vast majority of criminals aren’t even caught – and Labour are now proposing to abolish prison sentences of under a year, so even the few that get caught won’t suffer any real punishment.”
He has called for a “zero tolerance approach” and the greater use of technology, such as facial recognition technology, so that “Labour’s shoplifting epidemic can be stopped”.
Earlier this month, Home Secretary Yvette Cooper announced a significant expansion of the use of facial recognition tech by police forces in England and Wales, with 10 new vans being rolled out – though the move was criticised by civil liberties groups.

Jenrick slams justice system shake-up
Robert Jenrick, the shadow justice secretary, said the “damning stats explain why Britain feels lawless”.
He told Sky News: “Starmer’s plan to scrap prison sentences for shoplifters will only make this worse. We need the authorities to go after these criminals and lock them up for much longer to keep the public safe.”
The government has defended the proposals to largely end the use of shorter sentences, as recommended by the independent sentencing review, carried out earlier this year by former Conservative justice secretary David Gauke.
A Ministry of Justice spokesperson said: “Without further action, we will run out of prison places in months, courts would halt trials and the police [would] cancel arrests. That is why we are overhauling sentencing to make sure we always have the prison places needed to keep the country safe.”
