A RAPIST former police sergeant preyed on a colleague while she was asleep, it can be revealed.
Campbell Petrie, 50, was this week convicted of a total of nine charges involving a catalogue of physical and sexual abuse towards two women spanning between 2006 and 2022.
Sickening details of his crimes emerged at his trial at the High Court in Glasgow.
Petrie – who was promoted to the rank of sergeant during the offences – had denied the accusations, claiming he had been left “absolutely humiliated”.
Jurors heard how he got to know the latter victim from both working in the police.
He described her as a “bit starry-eyed” - but she was “pretty” and “out of his league”.
But Petrie, of the city's Muirend, discovered she was “interested” in him which he said was an “ego boost”, adding he was “more flattered than anything else” given the age gap.
Jurors heard it was “all very pleasant” initially between them when they got together.
But the woman told the court: “He did not like me working with men.”
Keep-fit fanatic Campbell started making weight jibes and tried to get the woman to stand on scales. He was also said to have raked through bins to check on what she had eaten.
The woman recalled that he warned he would harm her if she ever left him.
Petrie: “I would certainly not make threats to kill anyone.”
He also tried to ban her from going on social media and made her lose contact with friends.
Among other incidents – which included physical assaults - were Petrie hounding her at a friend's home despite being warned not to come near.
Prosecutors branded this incident “sinister” as he loitered at the back of the property in the dark.
Defence KC Edith Forrest quizzed him on sexual allegations made by this woman.
This included testimony that he raped her in the changing rooms of a leisure centre in Lanarkshire.
Petrie: "That never took place at all in the swimming baths, there or anywhere public."
He previously took advantage of the woman at a flat in Glasgow southside in 2011, having sex with her after she had been drinking and unable to consent.
The other woman who earlier suffered at his hands accused Petrie of “love-bombing” her after they met in a queue in a Tesco supermarket in Glasgow's Springburn while he was on shift.
He had “immediately found her quite attractive”.
She later came to see him at the city's Baird Street station and they remained in contact.
Despite all going well initially, the officer soon changed and started calling her names like “fat cow” and “s**t”.
The woman said: "He wanted me to be a skinny blonde."
The court heard he lost his temper in a bar in the city's west end and dragged her out after having earlier hit a man.
Forrest put to him: “She also went on to say how she woke up to find you (having sex with her). Did that happen?”
Petrie: “No.”
Forrest: “Her allegations – how do you feel about that?”
He replied: “I would never do that while someone was asleep. I find it absolutely sickening, devastating.”
Petrie also refuted claims he was overly physical with this victim, insisting anything he did was with “affection”.
He told jurors: “There was never any time she was forced to do anything. She was fully consenting.”
The trial heard evidence of a drunken Petrie being aggressive with the woman after a party.
He denied putting his hands around her throat.
Petrie was initially arrested in around 2009 following allegations made by this woman.
Police colleagues turned up at his door and he was held in a cell for up to five hours before eventually being released.
Forrest: “How did you feel at that time as a serving officer?”
Petrie: “Absolutely humiliated and confused. I had not done anything wrong.”
He remained in the force, got promoted before being arrested again in December 2022. Police Scotland state he was arrested in 2023.
Petrie retired from Police Scotland in December 2025 and had latterly been working in a friend's sports shop.
In cross-examination, prosecutor Paul Harvey KC initially put to Petrie that he preyed on the earlier woman while she was asleep.
The ex-officer denied this.
Harvey: "Who else said that you had sex with her while she was asleep?"
Petrie: "The other woman."
The advocate depute: "The truth is, both women we heard from told us that you had sex with them while they were asleep - there is a remarkable similarity in their accounts."
Petrie: "Yes, it's almost too convenient a similarity."
In his closing speech, Harvey urged jurors to convict Petrie.
The prosecutor: "Each woman spoke to Petrie doing sexual things to them while asleep.
“Each of them being pestered by Petrie, speaking about sexual offending against the background of a general long-term pattern of control and abuse.
“Each of them knowing what he could be like if he did not get his way."
After the verdicts, judge Alistair Watson told Petrie that the “gravity of the crimes committed cannot be overstated”.
Petrie had been on bail, but was remanded in custody as sentencing was deferred until next month.
The rapist winked and waved to family in the public benches as he was led to the cells.
