A woman and two men from Brampton are facing a rash of charges after the online dating app Tinder was used to lure a young woman into the sex trade.

Police are concerned "there may be more victims" in the human-trafficking and sex-crimes investigation, which began in December.

Toronto police say a young woman met a man on the Tinder dating website and he "procured" her into the sex trade and took her to a Mississauga hotel.

“He took photos of her in various stages of undress and posted advertisements for sexual services on the classified ad website Leolist,” police said in a statement issued Friday, Jan. 4.

Police allege that man made all of the arrangements for dates and sexual services and forced her to turn over all of her earnings to him.

"He assaulted her and threatened her family," police said in a release.

The same man, police say, then introduced the woman to another woman and man — his accused partners — who “took photos of her in various stages of undress, and posted advertisements for sexual services on the classified ad website Leolist,” police said.

The woman partner was also involved in arranging dates and sexual services and forced the woman to turn over all of her earnings.

“(These three) used deception, intimidation and fear to exercise control over the actions and movements of the woman,” said Toronto police Const. Caroline de Kloet in a news release.

Police also say one of the men in the group tried to lure another woman into the sex trade earlier through Tinder, but she refused, even though he kept harassing her.
