CHESTERFIELD, Mo. - A former Chesterfield police officer faces felony charges for allegedly setting up a camera in a men's restroom at a local gas station.

David Cerna, 33, was charged with sexual exploitation of a minor and second-degree invasion of privacy.

A media investigation tipped off the department that someone had been recording a men's restroom, Johnson said. The investigation found a website where the person had posted video of the restroom, and that led investigators to a Wentzville home owned by Cerna.

Wentzville police became involved when they said Cerna posted an ad on Craigslist inviting straight men to his house for unusual oral sex acts. Up to 60 men came to have sex through a barrier. They never knew a man was on the other side of the barrier.

The St. Charles County Cyber Task force got involved when Cerna posted all his videos on pornographic websites. Computers were recently seized from his home.

Cerna, a six-year veteran with the department, remains in custody on $50,000 cash-only bond.
