California football coach arrested after students make disturbing discovery at school

The discovery was made Thursday when a student and several classmates found the phone recording inside the locker room, officials said.

The students stopped the recording, deleted the video and turned the device over to a teacher.

By Thursday evening, a concerned parent then contacted Tracy police patrol officers, prompting school resource officers and detectives to open an investigation.

The following day, officers determined that the phone belonged to Pribble, who was arrested Friday.

The Tracy Unified School District placed Pribble on leave pending the outcome of separate

criminal and district investigations

, officials said.
