A former St. Louis County police officer who is already facing invasion of privacy charges was indicted for allegedly videotaping a teenage boy's genitals with a hidden camera, the St. Louis Post-Dispatch reported on Friday.

Prosecutors charged 33-year-old Chesterfield officer David Cerna with with sexual exploitation of a minor and second-degree invasion of privacy of multiple people for allegedly using the camera to film the teen and two other men under their clothes between August 2013 and this past January.

Authorities found footage after obtaining a search warrant and seizing Cerna's computer. He is scheduled to be arraigned on the latest charges against him on Oct. 22.

Cerna, a six-year veteran of the department, was fired this past June after being arrested and accused of invasion of privacy following a report by KTVI-TV connecting him to camera hidden inside a gas station restroom, where Cerna allegedly filmed customers using the facilities without their knowledge.

Another camera was found in a St. Charles County home, where Cerna allegedly lured anonymous men with an online posting promising the use of a "gloryh*le." Footage from both cameras was then reportedly posted online without the subjects' consent.

"It was rather shocking of course and took a minute to sink in," Chesterfield Police Chief Ray Johnson said at the time. "But we realized the severity of it and just set out to deal with it immediately as we would with any other suspect."
