A former Police Scotland officer has been jailed for 12 years for a series of violent sexual offences against women, just a day after another officer was convicted of three rapes committed in Shetland.

Campbell Petrie, 50, was sentenced at the High Court in Glasgow on Friday 16 October, following his conviction in September for offences committed between 2006 and 2023.

The sentencing comes immediately after serving officer Carmichael John Williamson, 32, was found guilty at the High Court in Edinburgh of four sexual offences, including three rapes, committed in Shetland between 2014 and 2022.

Although the two cases are entirely separate, their progression through Scotland’s courts on consecutive days has brought renewed attention to the serious issue of sexual offending within the police service.

Petrie was convicted of two charges of rape, indecent assault, assault with intent to rape and assault to injury and danger of life.

His crimes took place over a period of 17 years while he was a serving police officer.

He was arrested, charged and suspended from duty in December 2023, before retiring from Police Scotland in December 2025.

In addition to his 12 year prison sentence, Petrie will remain under supervision and monitoring in the community for a further three years following his release.

Assistant Chief Constable Tim Mairs, who leads Police Scotland’s Major Crime and Public Protection work, condemned Petrie’s actions and praised the courage of the women who reported his crimes.

He said:

“Petrie committed a series of severely abusive, exploitative and violent crimes towards women.

“His offending is in stark contrast to the professionalism and commitment of the officers who investigated him and ultimately helped bring him to justice.

“His victims have displayed great courage in reporting these matters, and our thoughts are very much with them today.

“I hope this sentence brings them some closure and comfort.

“This investigation shows the public that when matters of this nature are reported to us, regardless of who the perpetrator is that victims are listened to and supported as we take immediate action to identify and investigate those responsible.”

The sentencing follows Thursday’s conviction of Williamson, who was found guilty of offences committed while serving as a special constable and later as a police officer in Shetland.

Williamson was suspended from duty following his arrest in January 2024 and has been remanded in custody ahead of sentencing on 8 December.

In that case, Police Scotland’s Detective Superintendent Stevie Bertram acknowledged how difficult it can be for victims to report sexual offences, particularly when the person responsible is a police officer.

Both cases involve men who were entrusted with enforcing the law while committing serious criminal offences, raising difficult questions about public confidence and accountability within policing.

Police Scotland has stated that it is committed to investigating officers involved in criminal behaviour, whether serving or retired and whether offences occur during or outside working hours.

The convictions also underline the importance of victims being able to report abuse without fear that an offender’s position within the police will prevent an investigation.

For the women affected, the legal proceedings represent the outcome of investigations into serious offences committed over several years.

Petrie now faces a lengthy period in prison, while Williamson awaits sentencing following his conviction in the separate Shetland case.
