A police officer who could be Scotland’s Wayne Couzens killed himself after carrying out a 14-year spree of rapes and attempted murders, it was revealed today.

PC Alan Greer took his own life in May, but his ‘truly shocking’ offences were not revealed by Police Scotland until two months after his death.

The 47-year-old was a married father of one, with his wife and family said to be completely ‘oblivious’ to his double life.

Senior officers have insisted there were no ‘red flags’ to indicate years of offending.

But a source close to the investigation said: 'This could be Police Scotland’s Wayne Couzens moment.

‘Folk will be in a state of shock when they learn the full truth. I don’t think anyone really knows how bad it is yet.’

Greer killed himself on May 6 this year. His colleagues had only been told via the force’s intranet that he had died while suspended and under criminal investigation.

His first rape was of a woman in 2012 who had been a victim of crime. She came forward last year.

Detectives have discovered he had nine victims, five of whom were sex workers. In several cases, the sex attacks were so violent they constituted attempted murder.

He had used multiple pseudonyms and at least seven phones to hide his identity and offending.
