Derek Ridgewell Corruption Review: New Convictions, Ongoing Victim Search
6/30/2026, 11:01:26 PM
Core Event – Renewed Review of Convictions Linked to Derek Ridgewell
The Criminal Case Review Commission (CCRC) is currently examining three additional convictions tied to former British Transport Police (BTP) Detective Sergeant Derek Ridgewell. If the Court of Appeal quashes these cases, the total number of identified victims would rise to sixteen, with a further case already awaiting trial. The review follows a 2020 internal BTP investigation that highlighted gaps in record-keeping and identified other officers who may have colluded with Ridgewell.
Background & Context – Ridgewell’s Corruption and Past Investigations
Derek Ridgewell joined the BTP in 1964, later briefly serving in the Rhodesian Police before returning to London. Throughout the early 1970s he framed dozens of young, predominantly Black men for alleged “mugging” on the Underground, often using violence to secure confessions. Notable cases include the 1972 arrest of four men at Waterloo station and the “Oval Four” convictions at Waterloo in 1972, both later overturned. Ridgewell was never dismissed in 1973 despite multiple dismissed prosecutions, and he continued illicit activities, including mailbag theft and facilitating lorry robberies that generated roughly £4 million in today’s value. He was convicted of conspiracy to rob in 1980 and died in prison in 1982.

Official Statements & Responses
Assistant Chief Constable Charlie Doyle confirmed that BTP is “continuing to review records relating to the corrupt practices of former BTP Detective Sergeant Derek Ridgewell” and that “additional resources” have been allocated to the effort. The internal 2020 report acknowledged “victims of gross miscarriages of justice” and called for “full and unreserved public apologies,” while also noting the loss of relevant records that hampers further identification.
Criticism & Opposition
The BTP has faced criticism for not dismissing Ridgewell in 1973, for inadequate record-keeping, and for failing to interrogate officers who may have colluded with him. Critics argue that these shortcomings allowed Ridgewell to continue framing victims for decades.
On-the-Ground Reports – Victim Testimonies
Winston Trew, one of the “Oval Four,” said he believes “there could be more than 100 victims” and urged anyone wrongfully convicted because of Ridgewell to come forward. Another victim described life after exoneration as “living a nightmare before my conviction was quashed. It’s only now I can move on and talk about it.”
Conflicting Reports & Gaps
The 2020 investigation was unable to locate many historic files, leading to uncertainty about the exact number of additional victims. While some sources cite “more than 100” possible victims, official counts remain limited to the cases currently under review.
Verbatim Quotes
- “These cases would not have got here had it not been for the bravery of the families to take their cases to the Court of Appeal. Further work still needs to be done to identify and locate other victims.” — Matt Foot, solicitor, Appeal
- “I was living a nightmare before my conviction was quashed. It's only now I can move on and talk about it.” — Unnamed victim of Ridgewell’s corruption

What’s Next – Ongoing Review and Calls for Action
The CCRC will decide whether to refer the three pending cases to the Court of Appeal. BTP has pledged further resources to locate additional victims, and solicitors continue urging anyone affected by Ridgewell’s actions to submit evidence. The outcome may reshape understandings of police corruption in 1970s London and prompt broader reforms to historic case review processes.
