Authorities in Canada say Kris Allan Gowdy, 42, from Newcastle, Ontario has been charged with luring a child via computer, and attempted aggravated sexual assault.
Authorities say he was arrested earlier this month after befriending a boy online.
Investigators say he went to a home for the purpose of having sex, but when he showed up, the presumed 15-year-old was actually a police investigator.
Authorities say Gowdy is HIV-positive and he has travelled extensively over the last decade. Investigators say Gowdy had an extensive social media presence and they are concerned there may be more victims.
Gowdy was a church youth counselor in several areas including Rochester, New Brunswick, Ontario, Saskatoon, and Saskatchewan.
