Police in Guelph are looking to hear from any additional victims in connection with a sexual assault case which saw a man identify himself as an off-duty police officer.
On Aug. 20, police said a young teen, 15-years-old, claimed she had been sexually assaulted by a man in a photograph released by police Monday.
Early that August morning, she told police she and another young person had received a ride by a man in a vintage red truck. The pair had asked for a ride to the Guelph train station around 1:30 a.m.
“Police allege the male identified himself as an off-duty police officer and provided information that led the complainant to believe he was legitimate,” read an update from police.
“The male later drove the complainant and her friend around the city before the friend was dropped off at an unidentified location. The complainant was then driven to a nearby parking lot, where the alleged sexual assault occurred.”
Two days later, 69-year-old Brian Deboer was arrested when police said he attended the Guelph Police station.
Police are concerned there may be more victims and are looking for any information surrounding Deboer, particularly in cases in which he claimed he was police officer and/or in a red truck.
Anyone with information is asked to contact Detective Constable Jackie Ketteringham of the Guelph Police Service at 519-824-1212 or jketteringham@guelphpolice.ca.
