A USC professor suffered “some sort of an episode” that caused students to believe there was an active shooter at school, triggering the campus scare and police response on Monday, police said.
LAPD Deputy Chief Phillip Tingirides said the professor, who was not identified, told her students to lock the doors and get on the floor. Then, she began yelling, “active shooter.”
The search netted no evidence of a shooting or a shooter at school, authorities said. An all-clear was subsequently declared.
Tingirides said the professor was in LAPD custody.
