Two men have been killed in a murder-suicide at the University of California in Los Angeles earlier today.
LAPD Chief Charlie Beck said the shooting took place within a small office at an engineering building on campus.
Police responded to Boelter Hall science building this morning at 9:55am local time, and the university was put on lockdown.
The LAPD confirmed that two males were found suffering gunshot wounds, but it is not clear if they are students or staff.
Police Capt Andy Neiman told journalists: "If you are on campus, shelter in place.
"Lock yourself in a safe place until the authorities are able to get to you."
Students reportedly used belts and other objects in an effort to barricade doors during the campus lockdown, which unfolded during finals week.
