A major Police Scotland investigation has revealed that a serving police officer who died by suicide earlier this year was responsible for a series of sexual attacks on women spanning more than a decade.
Former police constable Alan Greer, 47, is believed to have assaulted at least nine women between 2012 and 2026, according to investigators. Authorities say more victims could still come forward as the inquiry continues.
The investigation began after a woman reported that Greer had raped her in her Glasgow home in 2012. She had originally contacted police to report another crime, and Greer was one of the officers who responded to the call.
Her complaint, made late last year, led Police Scotland's anti-corruption unit to reopen the case. Detectives reviewed police records and discovered that Greer had repeatedly accessed the woman's case file after the alleged attack.
Further inquiries uncovered evidence linking Greer to additional victims, including five women working in the sex industry, who investigators say were assaulted while Greer was off duty.
Police also examined Greer's mobile phone records and intelligence databases. Investigators found an earlier report from 2018 in which a Glasgow sex worker had described a violent customer linked to Greer's phone number.
Following that discovery, detectives obtained a search warrant for Greer's home. Officers seized electronic devices containing thousands of photos and videos. Police say the material indicates Greer had contacted hundreds of sex workers during his policing career.
Investigators are still reviewing the digital evidence and have already identified additional alleged victims. Police also found images showing two female police officers had been photographed inappropriately while attending training sessions.
According to officials, the level of violence described in some cases was so severe that, had Greer been alive, detectives would have considered seeking attempted murder charges alongside multiple sexual offence charges.
As the investigation gathered pace, police and social workers visited Greer's home on 5 May to assess the safety of his family. Greer died by suicide the following day.
Assistant Chief Constable Lynn Ratcliff, who is leading the investigation, described the evidence uncovered as "truly shocking" and said Greer had abused the trust placed in him as a police officer.
She praised the courage of the first victim, saying her decision to report the alleged assault was the key factor that uncovered the wider pattern of offending.
Police Scotland said there had been no previous warning signs that would have identified Greer's behaviour during his career. However, Ratcliff acknowledged that under today's stricter vetting procedures, Greer would not meet the standards required to join the force.
The investigation remains ongoing, and detectives continue to examine digital evidence while encouraging anyone with relevant information to contact police.
