A Tucson man who thought he was meeting a minor for sex was arrested Tuesday when police showed up instead.

Roy Combs, 30, was booked into the Pima County jail and faces one count each of aggravated luring a minor for sexual exploitation and attempted sexual conduct with a minor.

In January, the Tucson Police Department’s Internet Crimes Against Children Unit developed information that a man was using a social networking website to solicit underage juveniles for sex, Sgt. Chris Widmer, a spokesman for the Tucson Police Department, said in a news release.

Detectives initiated an investigation and were able to identify the suspect as Combs.

Tuesday, Combs went to a midtown location expecting to meet a juvenile for sex, Widmer said. Instead, detectives from TPD and agents from the U.S. Marshals Service arrested him.
