A former student of a private school in Torrance, California, is in custody after allegedly stabbing three staff members, attempting to stab a fourth person, and later making a bomb threat while under arrest, police said.

The former Switzer Learning Center student left the three staff members injured and triggered a major response from the Los Angeles County Sheriff’s Department Bomb Squad Monday.

The Switzer Learning Center is a nonpublic special education school that, according to its website, supports students from Kindergarten through 12th grade.

According to a statement posted on the Torrance Police Department’s Instagram page, officers responded around 8:15 a.m. local time to reports of a stabbing at the school on Amapola Court.
