Key Points
- PC Alan Greer, a former Strathclyde Police officer later exposed as a violent serial rapist, passed force vetting in 2009 despite a documented history of criminal behaviour towards women.
- Greer was investigated by Strathclyde Police in 2002 over inappropriate phone calls to a woman in Glasgow. In 2005, he received a formal Metropolitan Police caution for a similar offence against a woman in London.
- Police Scotland said the former Strathclyde Police vetting unit knew about the 2005 caution when processing Greer’s application, but it is unclear whether the 2002 incident was considered.
- Greer ended his own life in May 2026, days after his home was searched during Operation Submarine, an anti-corruption investigation into sexual assaults and attempted murders dating back to 2012.
- The number of identified victims has reached 15, including a woman who reported a crime in 2012 before Greer raped her at home, five sex workers subjected to extreme violence and two female police officers.
- Reviews found Greer was never re-vetted after Police Scotland was created in 2013, leaving him among 8,800 legacy officers who did not undergo later vetting checks.
- Police Scotland said its vetting procedures are now “markedly different”. An independent National Police Chiefs’ Council (NPCC) review will examine the decision to recruit Greer in 2009.
Glasgow (Glasgow Express) August 28, 2026 – A uk/police/">Glasgow police officer who was unmasked as a violent serial rapist passed vetting checks to join the force despite his official records detailing two separate reports of criminal behaviour directed at women.
PC Alan Greer ended his own life in May 2026, just days after a police raid on his property formed part of a major anti-corruption inquiry into offences spanning 14 years. It has now emerged that prior to joining Strathclyde Police in 2009, Greer had already been subject to two police investigations for harassing women via telephone, one of which resulted in a formal criminal caution.
As reported by Samantha Poling of BBC Scotland’s Disclosure unit, Greer was first investigated by Strathclyde Police in 2002 over allegations that he had made inappropriate and harassing phone calls to a woman in Glasgow. Although that file was submitted to the Procurator Fiscal, no formal prosecution followed. Three years later, in 2005, the Metropolitan Police investigated Greer for committing a near-identical offence against a woman in London, which culminated in Greer accepting a formal police caution.
Despite these prior warnings, Strathclyde Police recruited Greer in 2009. Police Scotland has now confirmed that staff in the legacy vetting unit were explicitly aware of his 2005 Metropolitan Police caution when his application was approved.
What Was The Extent Of PC Alan Greer’s Offending While Serving In Police Scotland?
As reported by William Gaddi and Kieran Webster of Glasgow Live, PC Alan Greer’s first known victim was a woman he raped inside her Glasgow home in 2012. The woman had originally called the police to report that she was the victim of an unrelated crime. Uniformed officers attended her address, recorded her statement, and departed. Hours later, Greer returned to the property alone while on duty, forced the victim into a sexual act, and raped her.
The victim came forward to report the historic attack late last year, which prompted Police Scotland to launch Operation Submarine—one of the largest internal anti-corruption and criminal investigations in the force’s history.
As detailed by the investigation, detectives discovered that Greer was using police computers to monitor system searches regarding specific phone numbers, attempting to track whether complaints had been lodged against him. Following his arrest in April 2026 and subsequent release pending further enquiries, investigators seized electronic devices from his home.
Analysis of those devices revealed thousands of explicit images and videos. Officers uncovered that Greer had frequented hundreds of sex workers throughout his policing career, aggressively assaulting many of them. The total count of verified victims has risen to 15, comprising the 2012 complainant, five sex workers subjected to extreme physical violence and attempted murder, two female police officers targeted for inappropriate photos during training exercises, and seven other women attacked off-duty.
Why Were Systematic Missed Opportunities Overlooked By Police Authorities?
As reported by The Herald, senior police officials initially claimed there were no missed opportunities to apprehend Greer sooner. Appearing before media outlets in July 2026, Assistant Chief Constable Lynn Ratcliff stated that there was “nothing to suggest that there have been any missed opportunities over the years” to detect his offending.
However, Police Scotland subsequently issued a clarification, asserting that Assistant Chief Constable Ratcliff’s comments referred strictly to Greer’s conduct during his active 17-year policing career, rather than the initial 2009 recruitment and vetting process.
As reported by STV News, a confidential police briefing document dated June 12, 2026, labelled under “Operation Submarine”, stated explicitly that under the current security framework, Greer “would not have been granted Recruitment Vetting.” The document was submitted to both the Scottish Government and the Scottish Police Authority (SPA). However, the specific details surrounding Greer’s legacy vetting failures were omitted during the SPA’s public board meeting on July 30, 2026.
Further structural flaws were highlighted by Craig Naylor, the Chief Inspector of HM Inspectorate of Constabulary in Scotland (HMICS). Speaking to BBC Scotland, Mr Naylor stated unequivocally that even under the standards of 2009, Greer’s record of behaviour towards women should have barred him from entering the police force.
When asked directly whether the decision to recruit Greer represented a missed opportunity, Mr Naylor responded: “Yes. My view is that he should never have got in at that point.”
It was also revealed that following the amalgamation of Scotland’s eight regional forces into Police Scotland in 2013, Greer was never subjected to routine re-vetting. A 2023 HMICS inquiry identified that Greer was among 8,800 legacy officers and staff—representing more than a third of the force’s entire workforce—who had never undergone updated background checks. Although Police Scotland subsequently initiated a “historic data wash” following English police vetting scandals, no red flags were triggered regarding Greer’s record at that time.
Background Of The Particular Development
The revelations surrounding PC Alan Greer represent one of the most critical structural failures in modern Scottish law enforcement history. The establishment of Police Scotland in 2013 under the Police and Fire Reform (Scotland) Act merged eight territorial forces, including Strathclyde Police, into a single national entity. However, this administrative consolidation left legacy gaps, specifically regarding how historical vetting files were transferred, maintained, and periodically reviewed.
In recent years, policing across the United Kingdom has faced intense public scrutiny over internal vetting procedures following high-profile criminal cases involving serving officers, such as Wayne Couzens and David Carrick within London’s Metropolitan Police.
In response, HMICS conducted a comprehensive review of Police Scotland’s vetting integrity in 2023, recommending stringent re-vetting protocols and enhanced background checks. Police Scotland has confirmed that the legacy 2009 Strathclyde Police recruitment decision will now be formally examined as part of an independent external review led by the National Police Chiefs’ Council (NPCC).

Prediction: How This Development Will Affect The General Public And Victims Of Crime
The exposure of PC Alan Greer’s vetting record and subsequent undetected crimes is projected to have profound consequences for multiple sectors of the public, particularly survivors of sexual violence, sex workers, and overall public confidence in law enforcement.
- Impact on Crime Victims and Vulnerable Women: The revelation that an on-duty police officer used his position to rape a woman who had called the police for help severely undermines public trust in emergency services. Survivors of domestic abuse and sexual assault may feel increased hesitation or fear when reporting crimes to Police Scotland, fearing potential abuse of power by attending officers.
- Impact on Sex Workers: With five of the identified victims being sex workers, this case highlights systemic vulnerabilities faced by marginalized groups when interacting with law enforcement. It is anticipated to increase demands from civil rights groups for specialized, independent reporting pathways for sex workers that do not rely directly on standard police channels.
- Impact on Police Officers and Workforce Policy: The broader workforce of Police Scotland will face heightened scrutiny and mandatory procedural changes. The force has already introduced annual integrity testing and compulsory re-vetting. Serving officers are likely to experience stricter internal monitoring, enhanced data-access auditing, and mandatory disclosures regarding historical cautions or civil complaints, as Police Scotland moves to close legacy vetting loopholes permanently.
