Police investigating the Horizon Post Office scandal have now identified seven suspects, with more than 45 people classed as “persons of interest”.
A “scaled-up” national team of officers has been in place for over six months as part of Operation Olympos – dedicated to looking at crimes related to the Horizon Post Office scandal.
The number of suspects has increased to seven since before Christmas, as part of a UK-wide investigation involving 100 officers.
Four have now been interviewed under caution.
Hundreds of subpostmasters were wrongfully convicted of stealing after faulty computer software created false accounting shortfalls in Post Office branches between 1999 and 2015.
Commander Stephen Clayman, Gold Command for Operation Olympos, described a “huge shift” in terms of their investigation and “significant progress”.

“We’ve got over four million documents that are going to rise to about six million documents,” he said, “but we’re beginning to methodically work through those and looking at individuals who are associated with certain prosecutions.”

He described a “pool of about 45 people plus” classed as “persons of interest”, with that number “expected to grow”.
He added that officers have questioned “some” in the past and “more recently” and are looking at the offences of perverting the course of justice and perjury.
The “wider pool” of persons of interest is made up of Post Office investigators, lawyers, and “management” across Fujitsu and the Post Office.

Post Office knew about faulty IT system
The team of officers will be identifying actions which could amount to criminal offences on both an individual and corporate basis.
Any decisions made on whether to charge will not happen until after the Post Office inquiry findings are “published and reviewed”.
The Operation Olympos officers are part of four teams – a London hub and three regional teams – who have been described as “highly motivated” across England and Wales.
Police Scotland and the Police Service of Northern Ireland are also helping.
Cmdr Clayman said that officers “will be building a robust case” to pass on to the Crown Prosecution Service.

He also added that, compared to the inquiry, his officers will have to “prove this to the criminal standard…a much, much higher standard”.
He described feeling “optimistic” and “confident” that the teams will have “some successful outcomes”, and said they are “working as hard and as quickly as (they) can”.
Teams are involved in what has been described as a “focused strategy which gets to the heart of the issues”.
Their investigations are being overseen by the National Police Chiefs’ Council and the Metropolitan Police.
Victims have also been told that the police will not be reinvestigating every case but “taking a speculative look at cases” to focus on key people involved and evidence for prosecution.
Operation Olympos is also making use of special software to help process the amount of evidence to sift through material in relation to key events and identified cases.
Of the four suspects interviewed under caution, two were questioned in late 2021, one in late 2024 and the most recent in early 2025.
A 43-year-old woman has been arrested on suspicion of murder after the death of two children in Stafford.
Police were called to a home on Corporation Street at around 7.30am on Sunday by West Midlands Ambulance Service.
Two children were pronounced dead at the scene, StaffordshirePolice said.
Detective Inspector Kirsty Oldfield said: “We are working hard to understand more about what happened leading up to these two children tragically losing their lives.
“We ask that people do not speculate at this stage as it is distressing for family and friends and could hinder our inquiries.
“We understand that this incident may cause concern in the local community. We don’t believe there is wider threat to the public at this time.”
The 43-year-old woman, who is from the Stafford area, remains in custody.
The force has not confirmed the ages of the two children. Their next of kin have been informed and are being supported by specially-trained officers, police said.

Watkins was previously stabbed in an incident at the same prison in 2023, suffering non life-threatening injuries after he was reportedly taken hostage by three other inmates before being freed by prison officers six hours later.
He was sentenced in December 2013to 29 years in prison, with a further six years on licence, after admitting 13 sex offences, including the attempted rape of a fan’s baby.
He also encouraged a second fan to abuse her child during a webcam chat and secretly stashed child sexual abuse videos, some of which he had made himself.
At the time, police described him as a “committed, organised paedophile”.
Having found fame in Welsh rock band Lostprophets, Watkins was arrested after his Pontypridd home was searched on orders of a drug warrant in September 2012.
A large number of computers, mobile phones and storage devices were seized during the search.
When sentenced at Cardiff Crown Court, the singer was told he was being given an extended sentence – and a judge said his crimes “plumbed new depths of depravity”.
