A serving Police Scotland officer, PC Alan Greer, who died in May, was a violent rapist responsible for a series of sexual attacks and attempted murders of women over at least 14 years, the BBC has revealed. The first known victim reported that Greer raped her in her Glasgow home in 2012 after she had called the police to report a crime.

This initial report, made late last year, triggered one of Police Scotland's most significant anti-corruption investigations. Detectives have since identified eight additional victims, five of whom were sex workers. These assaults occurred while Greer was off duty. It is also known that Greer utilized the services of hundreds of prostitutes throughout his career, and authorities anticipate that further victims will come forward.

Assistant Chief Constable Lynn Ratcliff, the gold commander for the investigation, described the findings as "truly shocking." She stated that Greer "clearly abused his power and has revisited someone that he's encountered in the course of his duties." Ratcliff emphasized the bravery of the initial victim, whose report was the "trigger point" for the investigation, enabling the identification of eight more victims.

The BBC Disclosure investigation into Greer's offending has brought these details to light. A source close to the investigation drew a comparison to the case of Wayne Couzens, a Met Police officer convicted of the rape and murder of Sarah Everard, suggesting this could be Police Scotland's "Wayne Couzens moment."

Greer, who moved to the UK from Australia in 1978, joined Strathclyde Police in 2009 before its merger with Police Scotland. He had a 17-year career with no prior disciplinary issues. He initially served as a uniformed response officer in Glasgow and later moved into officer safety training around 2016, instructing both new recruits and experienced officers.

At the time of his death at age 47, Greer was married with a child. His family and colleagues were reportedly unaware of his "violent double life." Senior officers have maintained that there were no opportunities to detect his offenses earlier.

The investigation began late last year when a woman reported an incident from 2012. She explained that after police attended a disturbance at her Glasgow home, one of the responding officers returned alone hours later and sexually assaulted her. Following her report, the woman reportedly disengaged from further inquiries, but her bravery initiated the extensive investigation.

Authorities are continuing to investigate the full extent of Greer's offending, with the expectation that more victims may be identified. The case raises significant questions about vetting, oversight, and the potential for abuse of power within law enforcement.
