IRVINE, Calif.—A teacher at Beckman High School in Irvine was arrested Feb. 27 on suspicion of hiding recording devices in a bathroom at the school.

Siu Kong Sit was arrested for possession of or manufacturing child pornography, burglary, and on two misdemeanor charges and was booked at the Orange County Jail, said Irvine Police Department Lt. Cathy Scherer.

According to police, a contracted maintenance worker found the devices inside a restroom near a pool at the school and turned the items over to the school’s administrative staff, which then called the police department. Officers determined the devices had recorded several victims while they were in the restroom, Scherer said.

During the course of their investigation, detectives determined Sit had installed the recording devices.

Scherer said police are attempting to locate additional victims based on additional evidence located on the devices.
