Two detectives from the British Transport Police (BTP) are facing an official investigation following allegations that they failed to adequately supervise or progress a criminal inquiry. The case in question involves sexual assaults committed by Simon Levy on the London Underground in October 2024.

According to reports, the investigation into the officers' conduct centers on whether they missed opportunities to intervene or properly manage the evidence during the initial stages of the case. The BTP has confirmed that the officers are being scrutinized for their professional performance during the period leading up to the subsequent murder charges brought against Levy.

While the specific details of the alleged procedural lapses remain under review, the investigation highlights concerns regarding police oversight in cases involving repeat offenders. The BTP has not provided a timeline for the conclusion of the internal probe, but the matter has drawn attention to the internal accountability mechanisms within the force. As of now, the detectives remain the subject of an active inquiry to determine if their actions—or lack thereof—contributed to the failure to stop Levy before his criminal activity escalated to murder.
