Liam Yeo
Introduction
Liam Yeo was a police constable with Thames Valley Police until fabricated records about a witness contact ended his career. Working with Incident and Crime Response Team 1 at Didcot Police Station, and having joined the force only in May 2023 as a student police constable, he was allocated an arrest handover in a drink-driving investigation in October 2024 and responded by making false and misleading entries in case documents about contacting a witness. The deception unravelled when another officer listened to the original 999 calls, and Yeo resigned before an accelerated misconduct hearing found he had committed gross misconduct and barred him from policing.
Background Information
Yeo joined Thames Valley Police in May 2023 as a student police constable and served with Incident and Crime Response Team 1 at Didcot Police Station in Oxfordshire. The unit responds to incidents and crimes in progress, work that depends on accurate case records: the MG6 documents and NICHE system entries Yeo later falsified are the records investigators and prosecutors rely on to establish what contact officers have actually had with witnesses.
The Controversy or Incident That Led to Their Cancellation
Misconduct findings, not criminal convictions. The findings below come from a Thames Valley Police accelerated misconduct hearing chaired by Chief Constable Jason Hogg, which found the allegations proven on the balance of probabilities. They are regulatory adjudications rather than court judgments, and no criminal charge against Yeo is reported in the sources cited here.
On 18 October 2024, Yeo was allocated an arrest handover concerning a drink-driving suspect who had been arrested the previous night and was in custody. He was required to make enquiries of a witness, identified in case papers as XX, who had called 999 at the scene. Instead of pursuing the statement, Yeo made false and misleading entries in an MG6 case document and on the force’s NICHE recording system. One entry stated: “XX is unable to provide a statement detailing this as when I have attempted to get this, admittedly late, he has not remembered if they were actively trying to move the vehicle.” Another recorded that the witness was “not sure if they were actively trying to drive the vehicle”.
The file was handed to a Justice Gateway Officer, who listened to the original 999 calls, became suspicious because they contradicted what Yeo had recorded, and in April 2025 created a task for Yeo to contact witnesses. When the log was later checked, it showed an entry claiming Yeo had spoken to witnesses with a “negative result which precluded the taking of a statement”. Another officer was instead tasked with taking the witness’s statement, which provided “key evidence” and allowed the criminal case to proceed. On 6 May 2025 the witness confirmed he had called 999 and spoken to officers at the scene, but had received no further police contact since.
Challenged by a sergeant, Yeo initially maintained that he had spoken to the witness by telephone and debriefed him, and that the witness could not remember the incident. An audit of the NICHE system then showed he had amended the MG6 that same day to remove the part saying the witness was unable to provide a statement. Questioned again on whether he had been truthful, Yeo admitted he had not. The BBC reported that the panel heard his admission that the information was untruthful “would have led to miscarriage of justice had it not been highlighted”.
Public Reaction and Consequences
Yeo resigned from Thames Valley Police with immediate effect on 20 July 2025, before the disciplinary process concluded. He did not attend the accelerated misconduct hearing on 5 August 2026, chaired by Chief Constable Jason Hogg, but confirmed by email on 29 July 2026 that he accepted his conduct amounted to gross misconduct. Hogg found breaches of four Standards of Professional Behaviour — Honesty and Integrity, Duties and Responsibilities, Orders and Instructions, and Discreditable Conduct — and ruled that Yeo would have been dismissed without notice had he remained a serving officer. His name will also be placed on the public police barred list.
In his findings, Hogg said Yeo’s behaviour was “intentional and deliberate”, that his culpability was high, and that there was “ample evidence” it fell “far below” the standards expected of a police officer. “This case is straightforward, the officer’s conduct has been proven, and he has admitted the behaviour,” he said, adding that Yeo’s dishonesty on the MG6 “would have led to miscarriage of justice had it not been highlighted”, and that “the only appropriate sanction in this case is that the former officer would have been dismissed had he remained a serving officer.”
Current Status
Yeo is a former police officer who resigned on 20 July 2025 and, following the 5 August 2026 hearing, has been found to have committed gross misconduct and barred from the profession, with his name due to appear on the public police barred list. The criminal drink-driving case he had compromised was saved: the witness statement obtained by another officer provided key evidence allowing it to proceed. No criminal prosecution of Yeo is reported in the sources; the recorded outcome against him is the misconduct adjudication.
Impact on Their Career/Life
Yeo’s policing career lasted just over two years, from his May 2023 start as a student police constable to his July 2025 resignation, and ended not with a dismissal hearing he contested but with his own written acceptance that his conduct amounted to gross misconduct. The gross misconduct finding and barring mean he cannot work in policing again. The panel’s published reasoning was stark: by creating false records, misleading colleagues and compromising an active criminal investigation, his conduct had the potential to undermine public trust and confidence in the police service and bring discredit upon Thames Valley Police.
