In 2026, the Offender Database recorded that Oscar Devlin, 25, of Admiral Street, Lewisham, London, was jailed for two years and seven months after a predatory campaign against two young girls. On Tuesday, 24 February 2026, the defendant appeared at Woolwich Crown Court for sentencing. The court reported that Devlin was a Metropolitan Police trainee and a volunteer for St John Ambulance when he began grooming a 14-year-old girl in late 2023.
The investigation established that Devlin was seen kissing and cuddling the 14-year-old victim, who was later discovered partially clothed in his bedroom. The Metropolitan Police reported that Devlin was dismissed from the force following his initial arrest. However, while on bail in December 2024, the prosecution reported that he used a fake name on Snapchat to target an 11-year-old girl, coercing her into sending over 40 explicit images and repeatedly attempting to arrange a meeting in London.
Judicial Findings and Investigative Detail
The court reported that Devlin exploited his positions of trust to facilitate his access to children. Woolwich Crown Court heard testimony from the mother of the 11-year-old victim, who described the horror of discovering the messages and the damage done to her daughter’s childhood security. The prosecution reported that Devlin only ceased his contact with the younger child after the victim’s mother intervened and contacted the police in Lewisham, London.
The judge noted that a probation report indicated Devlin showed no genuine remorse and appeared “more sorry that he had been caught.” For his actions in Lewisham, the defendant pleaded guilty to engaging in sexual activity with a child and sexual communication with a child. The judge noted that the 31-month custodial sentence was necessary to address the fact that Devlin continued to abuse children even while under investigation and on court bail.
Sentence and Statutory Requirements
For his crimes in England, Oscar Devlin was handed:
- Custodial Sentence: Two years and seven months (31 months) in prison.
- Sex Offenders Register: Notification requirements were activated for life.
- SHPO: An indefinite Sexual Harm Prevention Order.
- Judicial Oversight: Sentenced at Woolwich Crown Court following guilty pleas.
- Professional Barring: Dismissed from the Metropolitan Police and barred from roles involving children.
- Origin: Admiral Street, Lewisham, London.
Monitoring and Public Protection
Devlin is managed under Multi-Agency Public Protection Arrangements (MAPPA) by the Metropolitan Police and the prison estate. Due to his history of reoffending while on bail and his background in law enforcement training in Lewisham, his management is subject to high-level oversight by the Public Protection Unit.
As a member of the Sex Offenders Register, Devlin must comply with notification requirements regarding his identity and residence for the remainder of his life. Authorities state that his persistence in targeting girls as young as 11, combined with his lack of remorse, necessitates permanent and stringent monitoring of his digital activity. Any further sexual misconduct or breach of his indefinite SHPO in Lewisham, Woolwich, or elsewhere will result in immediate arrest and a return to the court system for a significantly lengthier term of incarceration.
