Students and staff at a middle school in Menifee were sheltering in place after a threat was made to the campus Monday morning.

The threats against Ethan A. Chase Middle School were apparently made on social media and “out of an abundance of caution” a temporary shelter in place order was implemented, according to the Menifee Police Department.

The order was lifted around 11 a.m. and school activities returned to normal, police later said.

Authorities and district officials did not offer any more information about the nature of the threats.
