A note with a bomb threat brought the evacuation of a large community college and a nearby high school in the suburbs east of Los Angeles, but classes at the college are resuming after an investigation.
Officials say the note threatening to set off bombs at Mt. San Antonio College and Walnut High School was found in a bathroom at the high school Thursday morning.
The college campus in Walnut was evacuated about 12:30 p.m. but classes were set to resume about 4:30 p.m.
The high school about three miles away was on lockdown for about two hours before students were sent home.
Police and sheriff's deputies are investigating the threat. No arrests have been made.
