A Scottish police officer who took his own life in May 2026 has been identified as a serial rapist who assaulted at least nine women over a 14-year period. The case has triggered one of Police Scotland's largest anti-corruption inquiries (The Guardian).

PC Alan Greer, born in Australia in 1978, joined Strathclyde Police in 2009. He accumulated 17 years of apparently unblemished service before the investigation that would expose him. When he died by suicide on 6 May 2026, he was 47 years old, with a wife and child. His family and colleagues were reportedly oblivious to his violent double life.

The investigation began when Greer's first known victim came forward in late 2025. She was a woman he had raped in her Glasgow home in 2012 after she called police to report being the victim of a crime. Her disclosure set in motion an anti-corruption probe — an internal investigation focused on police misconduct — that would ultimately uncover eight additional victims. Five of those were sex workers whom Greer attacked while off duty. A BBC Disclosure investigation separately revealed that Greer had used hundreds of sex workers throughout his police career, and investigators anticipate identifying more victims as their work continues.

Once the 2012 victim's report was filed, the anti-corruption unit traced her original emergency call and identified the officers who had attended. They discovered that Greer had repeatedly accessed and monitored her crime file in the years after the assault. Detectives then obtained Greer's mobile phone number and ran it through police intelligence databases. That query surfaced 2018 intelligence from a Glasgow sex worker indicating the number's owner was a violent customer — a piece of information that had not previously been connected to a serving officer.

As the investigation deepened, detectives monitored every keystroke Greer made on police computers. They found he had been searching for traces of a complaint linked to a phone number belonging to a Glasgow sex worker. A sheriff (a Scottish judicial officer with the authority to issue warrants) subsequently authorised a warrant to search Greer's home and seize his devices. Officers found thousands of graphic videos and images on those devices.

Investigators have not yet processed half of the seized files. From what they have reviewed so far, they have identified five sex workers who were seriously sexually assaulted and two female police officers whom Greer photographed inappropriately during training. The violence in some of the assaults was severe enough that, had Greer survived, police would have sought charges of attempted murder.

Assistant Chief Constable Lynn Ratcliff, who served as gold commander (the senior officer overseeing the operation) for the investigation, confirmed the inquiry found "truly shocking" evidence. She stated that Greer had abused his power by revisiting someone he had first encountered in the course of his duties. Ratcliff also said no red flags had been missed but acknowledged that Greer would not pass vetting checks under current standards.

The timeline of Greer's death bears scrutiny. On 5 May 2026, social work officers accompanied by local police visited Greer's home to ensure his family were not in danger. He died by suicide the following day.

A source close to the investigation drew an explicit parallel to the Wayne Couzens case, calling this "Police Scotland's Wayne Couzens moment." Couzens, a serving Metropolitan Police officer, murdered Sarah Everard in 2021 in a case that exposed systemic failures in police vetting — the process of checking an officer's background and conduct — and the handling of warnings about predatory officers.

The comparison carries institutional weight. Both cases involved serving officers who exploited their position to identify and target victims. Both raised questions about whether intelligence that could have flagged a dangerous officer existed within the system but was never acted upon. In Greer's case, the 2018 intelligence from a Glasgow sex worker, which described the owner of his phone number as a violent customer, sat in police databases for roughly seven years before the anti-corruption inquiry surfaced it.

The institutional questions do not stop there. Greer repeatedly accessed his first known victim's crime file after the 2012 assault without triggering any audit or alert. He used police computer systems to search for complaint traces linked to a sex worker's phone number while under investigation. And he photographed female colleagues inappropriately during police training, a setting where his conduct would have been visible to others. ACC Ratcliff's assertion that no red flags were missed, paired with her concession that Greer would fail today's vetting standards, points to a gap between what the system could detect and what it actually caught.

The broader context here is one of institutional accountability. Police Scotland now faces the same scrutiny that fell on the Metropolitan Police after Couzens: whether its vetting, intelligence management, and professional standards regimes are adequate to identify predatory officers before harm escalates, or whether they remain reactive, waiting for a victim to come forward before connecting threads that were already present in the system.
