Toronto police are looking for a man who apparently failed to warn his sex partner that he is HIV positive before their sexual encounter.

Police launched an investigation after the wanted man and a 23-year-old man had “sexual relations” after meeting at an establishment near Church and Wellesley streets Sunday at about 4 a.m.

After the sexual encounter, the man informed the 23 year old that he is HIV positive, police said in a news release Monday.

Police believe there may be additional victims, and they are asking anyone with information to call investigators in what is being described as a sexual assault investigation.

The unidentified man is 35 to 40 years old and five-foot-eight with a slim build, shaved head and a tanned complexion, according to police.

He may have a small tattoo on his shoulder.

Anyone with information is asked to call detectives at 416-808-7474 or Crime Stoppers anonymously at 416-222-TIPS (8477).
