A former University of Wisconsin student pleaded guilty Tuesday to two counts of making threats against women.

Devan McCambridge, 20, posted a Craigslist ad in which he pretended to be a woman looking for sex with another woman.

McCambridge pleaded guilty to threatening two women who answered the ad, telling them he would post their nude photos online if they did not have sex with him, according to the Wisconsin State Journal.

McCambridge was arrested May 3, 2014 after a third woman agreed to meet with him. He was charged with making threats and attempted third degree sexual assault and pleaded guilty in September 2014 to attempted third degree sexual assault.

More charges were added in October when two other women contacted the police, according to the State Journal.

Two counts of attempted third degree sexual assault were dismissed as part of a plea agreement, according to the article. Each conviction carries up to six years of prison and supervision.
