A community college in northeast Los Angeles County was evacuated and a nearby high school put on lockdown Thursday morning after multiple bomb threats were made to both campuses.

According to the Los Angeles Sheriff’s Dept., a note was found in a bathroom at Walnut High School at around 10:20 a.m. containing a message stating a bomb would go off on the campus and at Mt. San Antonio College about a mile away. The note warned the bomb would go off at 2:45 p.m. at both sites, the San Gabriel Valley Tribune reports.

Walnut High was put on lockdown before the “all clear” was called at 12:40 p.m., the LASD stated. Students were let go at 1:20 p.m.
