Christopher Ferguson, who formerly served with Police Scotland, was convicted on Thursday, June 13 at Hamilton Sheriff Court.
The 31-year-old carried out the crimes against multiple women in the Lanarkshire area.
After receiving a complaint, the force launched an investigation and took steps to identify more of his victims.
He was arrested and charged in 2021 and suspended from his job immediately.
Ferguson is due to be sentenced on Thursday, July 11, 2024.
Following his conviction, Assitant Chief Constable Stuart Houston slammed the actions of the former officer and commended his victims for reporting him.
He also assured the public that criminality or misconduct by officers would not be tolerated.
He said: “My thoughts are with those who survived the appalling abuse by Christopher Ferguson and I hope this conviction provides them with some measure of closure. I commend their strength in reporting these crimes and bringing him to justice.
“We understand how difficult it can be to report these kinds of offences, particularly when the perpetrator is a police officer, but I want the public to be reassured that all reports are thoroughly investigated, no matter when the offending took place or who is involved.
“It is right that policing is held to high standards at all times and we will always support officers and staff acting with our values and standards at heart. The onus is on policing to build and maintain public confidence and consent which is critical in our ability to keep our communities and citizens safe.
“Criminality or misconduct by officers or staff damages public confidence and there is no place in policing for those who do not uphold our values.”
