A Mount Carmel High student was arrested at the Rancho Penasquitos campus Friday on suspicion of making a bomb threat against his school.
San Diego police took the 15-year-old into custody about 10 a.m., SDPD public-affairs Lt. Kevin Mayer said. The youth, whose name was withheld, was expected to be booked into juvenile hall on suspicion of making a criminal threat, the lieutenant said.
The teen allegedly had made the menacing statement earlier in the week via a written message on a boy's restroom stall door, claiming that an explosion would occur during fifth-period classes Friday afternoon.
Though police found no evidence that the threat was valid, officers were sent to the school Friday morning to monitor the day's activities as a precaution, Mayer said.
