Ryerson University in Toronto has put up notices around campus seeking information after a woman was sexual assaulted near the downtown campus last week. Police say a 27-year-old woman was picked up on Yonge Street between Dundas and Gerrard on the evening of Jan. 3 by six men in a black minivan with tinted windows. She was driven to a house somewhere in the Yonge and Eglinton area, sexually assaulted and then released. Police haven’t said whether the woman got into the van voluntarily. Detailed descriptions of the six suspects are available here.
