guelph (Oct 16, 2008) -- A Guelph man already facing charges of possessing child pornography has been arrested again after police allegedly uncovered photos of the man sexually abusing a young boy. The 33-year-old man was arrested last April during a child porn investigation. The new charges, laid last week, include sexual assault, sexual interference, engaging in anal intercourse and making child pornography. Guelph Police Const. Bruce Hunter said it took some time for investigators to go through thousands of images.
