Police Scotland officer PC Alan Greer, who died in May, was a violent rapist who attacked at least nine women over a period of 14 years, a BBC investigation has revealed. The inquiry was triggered when a woman reported a rape that occurred in 2012, after she had initially called the police to report a crime at her home. This disclosure led to one of Police Scotland's largest anti-corruption investigations, uncovering eight additional victims, five of whom were sex workers attacked while Greer was off duty. Investigators anticipate that more victims will be identified, as Greer is understood to have used hundreds of sex workers throughout his police career. Assistant Chief Constable Lynn Ratcliff described the findings as "truly shocking," noting the abuse of power by the officer. Greer, who had 17 years of service, was reportedly unknown to his family and colleagues for his violent double life.
