The Bancroft Middle School campus was under a precautionary lockdown Tuesday afternoon after the school received a telephone call about a shooting and bomb threat that ultimately turned out to be false, authorities said.

Long Beach police officers responded to the school after they received a call about the threat at about 12:27 p.m., police spokesman Richard Mejia said.

Officers cleared the campus and searched for anything related to a firearm or explosive device, but no threat was found, according to Mejia.

A message on the school’s website said the lockdown ended at about 1:30 p.m.

“Our students remained safe, and we have resumed normal operations,” the message read.
