Hundreds of residents staying at the University of California, Los Angeles were evacuated from their dorms Wednesday night after a phoned-in bomb threat to the campus' recreation center.
Fire alarms went off and school officials alerted residents through Twitter and text alerts just after 10 p.m to leave their dorms and evacuate to Drake Stadium as a precaution for an unspecified emergency.
Someone had called in for a bomb threat toward the school's Sunset Canyon Recreation Center, said UCLA spokesman Brian Haas.
At 12:20 a.m. Thursday, UCLA officials said the threat was unfounded and did not find a suspicious advice, according to the college in Westwood, a neighborhood in the northern central region of West Los Angeles.
Residents were allowed to return to their dorms and "resume normal activities," according to the school's emergency alert system.
Aerial footage showed hundreds of students streaming into the stadium, gathering on the soccer field and on the bleachers.
Vikatoria Lulio, who is attending UCLA for a summer program, told NBC4 she was outdoors practicing for a talent show when a woman told her group to evacuate to Drake Stadium. John Pardon, a math professor from Princeton University, said he was sleeping when his residence hall's fire alarms started blaring.
