BERKELEY, Calif. (AP) - Officials say students at the University of California at Berkeley are still not being allowed back on campus following an explosion from a power outage on campus.
UC Berkeley spokesman Dan Mogulof says the explosion occurred Monday evening in an underground electrical vault outside California Hall as power was trying to be restored on campus.
Mogulof says the explosion sent one person to the hospital with minor burns as three others also received minor burns but refused treatment.
Mogulof says the blast may have been caused by an underground copper wire theft at a campus substation last week causing more damage than initially thought.
Fire crews have also rescued about 20 people stuck in dormitory elevators as a result of the outage that also led to a mandatory evacuation on campus.
It's still unclear when classes will resume.
