The car he was driving was followed through south London by an unmarked police car with no lights or sirens.
He then turned into Kirkstall Gardens, a narrow residential street, where there was a collision between the vehicle he was in and a marked police car that was waiting for him at the scene.
An officer who was in that marked vehicle – referred to as NX121 for legal reasons – fired one shot through the windscreen, hitting Mr Kaba in the head.

It later emerged that the Audi Mr Kaba was driving – which did not belong to him – had been linked by police to a firearms incident the previous day.
The Independent Office for Police Conduct (IOPC) opened an investigation into the case, which lasted nearly seven months, before handing over a file of evidence to the Crown Prosecution Service (CPS) in March.
The officer – who has not been named – will appear before Westminster Magistrates’ Court on Thursday.
Rosemary Ainslie, head of the CPS Special Crime Division, said: “Following a thorough review of the evidence provided by the IOPC, the CPS has authorised a charge of murder against a Metropolitan Police officer following the death of Chris Kaba.
“The CPS reminds all concerned that criminal proceedings against the officer are active and that he has the right to a fair trial.
“It is extremely important there should be no reporting, commentary or sharing of information online which could in any way prejudice these proceedings.”
In a joint statement, the family of Mr Kaba said they “welcomed” the charging decision.
“Chris was so very loved by our family and all his friends,” the family said.
“He had a bright future ahead of him, but his life was cut short. Our family and our wider community must see justice for Chris.”
However, the Metropolitan Police Federation, which represents rank and file officers in the force, said the officer in question retained their “full support”.
“Being a firearms officer in London is one of the world’s toughest jobs,” the federation said in a statement.
“Officers, who volunteer for the role, know the responsibility and accountability that come with it.
“We note today’s statement from the CPS in relation to one of our firearms colleagues and make no further comment on that at this time.
“What we will say is that this decision will leave serving Metropolitan Police colleagues concerned as they go about their incredibly difficult and dangerous work.”
Deputy Assistant Commissioner Helen Millichap, of the Metropolitan Police, described the announcement as a “significant and serious development”.
“We have fully supported the IOPC investigation as it has worked to establish the facts,” she said.
“We must now allow the court process to run its course, so it would not be appropriate for me to say more at this stage.”
The Metropolitan Police said the officer remains suspended from duty and that any misconduct matters would be dealt with after the conclusion of criminal proceedings.
The force also said it would not release the name or age of the officer due to an anticipated anonymity request expected to be put forward on behalf of the defendant.
The family of a nine-year-old girl stabbed to death have said she was a “beautiful soul” who was brave, kind-hearted and “always put a smile on people’s faces”.
Police were called to Lime Close in Weston-super-Mare, Somerset, just before 6.10pm on Monday, where Aria Thorpe had suffered a single stab wound.
The child was pronounced dead at the scene.
In a tribute released by Avon and Somerset Police on Friday, the girl’s family on her mother’s side said: “For those who didn’t have the privilege of knowing Aria, she was the most beautiful little soul – happy-go-lucky, full of light, and joy.
“She loved to sing and dance, and she took such pride in dressing up, always wanting to look just like her mummy.”
Tom Thorpe, the girl’s father, said: “It’s hard to put into words how devastating it is, our little Aria, that you’re up there with the angels looking over us.”
It comes as a 15-year-old boy charged with Aria’s murder appeared in court.

Aria was a ‘precious girl’
In their statement, Aria’s family on her mother’s side said her death “has devastated us beyond words”.
“Our hearts are broken in a way we never imagined possible,” they added.
“As a family, we are holding one another close and doing everything we can to support each other through this unimaginable time.”
They said they were “truly touched by the lovely messages we have received”, before asking “that our privacy is respected, as we try to come to terms with the terrible loss of our precious girl”.

‘Wacky ways and outright madness’
Mr Thorpe said: “How sad it’s going to be not hearing ‘Dad, how long left?’ on our long journeys back and forth at weekends.
He then said that Aria was “such a brave, kind-hearted and a beautiful innocent soul”, and “always put a smile on people’s faces with your wacky ways and just outright madness”.
Mr Thorpe added: “Your other little family down here in Portsmouth will forever miss you.
“We’ll miss you begging to go outside, even in the pouring rain just to have as much fun as possible in the little time we had at weekends.
“You will be greatly missed, you special little angel. A life gone far too early but I hope a life lived well. We all love you dearly. Goodnight darling.”
Teenager in court
Meanwhile, a 15-year-old boy charged with Aria’s murder appeared at Bristol Crown Court on Friday, where he was remanded.
The teenager, who cannot be named because of his age, was arrested in the Somerset village of Worle at 6.19pm on Monday.
He is next due in court on 16 March 2026. Appearing via video link from youth detention accommodation, he spoke only to confirm his name.
Judge Peter Blair KC set a provisional trial date for 15 June during the hearing.
David Walliams has been dropped by his publisher HarperCollins UK.
A spokesperson for the company said that “after careful consideration, and under the leadership of its new CEO, HarperCollins UK has decided not to publish any new titles” from Walliams.
“HarperCollins takes employee well-being extremely seriously and has processes in place for reporting and investigating concerns,” the spokesperson added.
“To respect the privacy of individuals, we do not comment on internal matters.”
The publisher announced in October that it had appointed Kate Elton as its new chief executive, following the departure of former boss Charlie Redmayne.
The 54-year-old, who shot to fame with the BBC sketch show Little Britain, is one of the country’s best-selling children’s authors.
He has written more than 40 books, which have sold more than 60 million copies worldwide and been translated into 55 languages, according to his website.
His first children’s book, The Boy in the Dress, was published by HarperCollins in 2008.
Walliams is also known for Come Fly With Me, another BBC sketch show, and was formerly part of the judging panel for Britain’s Got Talent.
He was awarded an OBE in 2017 for services to charity and the arts.
Walliams has been contacted for comment.
