A Border Patrol supervisor accused of hiding a video camera in the women’s bathroom at the agency’s station in San Diego pleaded not guilty Thursday.

U-T San Diego reports that Armando Gonzalez, 46, pleaded not guilty to 19 counts related to the camera.

Authorities said at least a dozen women were captured on at least 170 videos, and the identities of some of the victims are still unknown.

Gonzalez maintains he installed the motion-activated cameras to investigate suspicions that an employee was using illegal drugs.

“He’s been a very good employee for the Border Patrol for two decades,” Anthony Colombo, who represented Gonzalez on Thursday, said.
