MADISON, Wis. -

University of Wisconsin police are looking for victims of a student they say used Craiglist to try to extort sexual favors from women.

Police said Devan McCambridge, 19, of Saukville, would pose as a woman on Craigslist to ask other women for personal information and explicit photos. He would then threaten to post the information and photos if they didn’t do what he asked.

A police spokesperson said McCambridge also posed as men and targeted men.

UW police said they worked with a victim to arrange a meeting with McCambridge and arrest him. He was arrested on May 3 on suspicion of third-degree sexual assault and threatening a victim.

Police said they believe there are other victims. They ask those who believe they might be victims to call police at 608-264-2677.
