A South Florida police captain has been arrested on charges that he forced a 15-year-old girl to disrobe so he could check whether she was having sex.

Broward County prosecutors say 46-year-old Miramar police Capt. Juan De Los Rios is facing two counts of lewd and lascivious conduct by an adult against a minor. Each count carries a potential 15-year prison sentence.

Authorities say De Los Rios encountered the girl and a 19-year-old man in the back seat of a car. The two told him they were just talking and not having sex. But prosecutors say De Los Rios told the girl to take off her clothes so he could make sure.

A 28-year veteran, De Los Rios is suspended without pay.

Court records did not list a defense attorney.
