York Regional Police have charged a 26 year old Richmond Hill man with a number of sexual offences, and now officers are worried there could be more victims out there.
Roman Krouglov would troll online classified websites and post in the 'casual encounters' section with the reply email of firstname.lastname@example.org.
The investigation originally started in February of this year when police were called to a home in Richmond Hill where it's believed Krouglov allegedly assaulted a woman, and threatened her with death.
Digging a little further, police determined that back in October of 2011, Krouglov allegedly had unprotected sex with a minor, while knowing he was HIV positive.
The young woman was then infected with the disease.
He's been charged with sexual interference, aggravated sexual assault, assault, assault with a weapon, uttering threats to cause death.
Police fear there could be a history, and there could be 'quite a few incidents' with more victims out there.
Constable Andy Pattenden wanted to remind any potential victims, that there is no statute of limitations for sexual offences and offenders can be prosecuted well after the date of the offence.
