Two Metropolitan Police officers are being investigated by a watchdog over alleged failures in their handling of a serial sex offender who murdered two women. Simon Levy, 40, was on bail and being monitored by police when he committed a violent rape in January 2025 and killed Carmenza Valencia-Trujillo, 53, in March and Sheryl Wilkins, 39, five months later.

The Independent Office of Police Conduct (IOPC) confirmed that a police constable is under a gross misconduct investigation, and a detective sergeant is subject to a misconduct investigation, relating to the management of Levy. The Metropolitan Police, British Transport Police, and the Crown Prosecution Service (CPS) have all acknowledged significant shortcomings in the case.

Levy, from Tottenham, north London, was found guilty at the Old Bailey on Friday of two counts of murder, two counts of rape, grievous bodily harm with intent, and non-fatal suffocation. He was remanded into custody ahead of his sentencing on August 12. The IOPC's investigation began in January following a voluntary conduct referral from the Metropolitan Police and is ongoing.

The watchdog is examining the management of Levy over a four-year period, from his first conviction in September 2021 for sexual assault charges up to his arrest in September 2025. Levy had been released from prison on licence in February 2023 and was briefly returned to custody in May 2024 after being accused of rape and breaching his licence conditions, but he was not charged at that time.

During his trial, jurors heard that Levy had a string of convictions for attacking women dating back to July 2018, including an assault on a prison officer in 2022. The IOPC stated it is examining whether action could or should have been taken to prevent his reoffending and if all officers involved followed policies, procedures, and training.

The IOPC is also assessing if any learning, whether individual, force-wide, or national, or other changes should be implemented in light of the events under investigation. The issuing of misconduct or gross misconduct notices does not necessarily mean disciplinary proceedings will follow, the watchdog added.

Detective Chief Inspector Neil John, who led the investigation, spoke outside court on Friday, describing Ms. Valencia-Trujillo and Ms. Wilkins as much-loved women. He praised their families for their dignity and resolve. DCI John also commended the surviving victim for her bravery in providing vital evidence.

He directly appealed for any further victims of Levy to come forward. Despite the convictions, the investigations into the handling of Levy by police continue, raising questions about systemic failures in managing known sex offenders.
