A shooting that left two men dead at the University of California, Los Angeles (UCLA) and led to a massive response on the campus in a bustling part of LA was a murder-suicide, authorities said.
Police chief Charlie Beck declared the campus safe about two hours after authorities received an emergency call.
The shooting happened in a small office in an engineering building called Boelter Hall, and a gun was found along with what might be a suicide note, he said. No names have been released.
Hundreds of officers from multiple federal and local agencies swarmed the campus, which had been placed on lockdown.
Teams in tactical gear looking for victims and suspects ran across campus, some with weapons drawn, and stormed into buildings.
People emerged from buildings with their hands raised or behind their heads.
The shooting occurred the week before final exams at UCLA, a major campus of the University of California system with about 43,000 students.
Many students posted to social media, many to let friends and family know they were safe.
Some described frantic evacuation scenes and a large police response. Others wrote that their doors were not locking and posted photos of items such as photocopiers pushed up against them.
