Homer Rogers, the assistant director of information technology at the private school, pleaded not guilty Friday in Waltham District Court to a charge of secret video surveillance of a partially nude person. He was released on personal recognizance.
According to a police report, school officials found a video camera and recorder hidden in the girl's bathroom. The report says a camera was placed in the insulation of a pipe aimed toward a toilet.
Police said Rogers was arrested Thursday after interviews with witnesses.
Rogers' attorney, Robert Casey Jr., didn't immediately return phone calls.
