The entire University of California, Los Angeles, campus was placed on lockdown after a shooting on Wednesday morning that left two people dead.
Law enforcement sources confirmed to CBS News that it was a murder-suicide involving two men. A note and a gun were recovered, police sources say. The incident took place inside an office inside the engineering building.
The Los Angeles Police Department said earlier in the day the situation led to a "citywide Tactical Alert," but that no additional suspects have been spotted.
Police chief Charlie Beck said that the situation on campus is now safe, but despite the lack of other suspects they are continuing their search of the campus "out of an abundance of caution."
The identities of the deceased have not been released.
A university-wide alert system for parents and students sent out a warning over Twitter at 9:58 a.m. local time.
Dozens of students and professors took to social media to give updates as the situation unfolded.
The school's student-run student newspaper, the UCLA Bruin, reports on its Twitter account the shooter is a white male.
The White House said in a statement President Obama has been briefed on the situation.
The school on the west side of Los Angeles is a flagship of the University of California system, with about 43,000 students. It's currently the week before final exams. Classes have been canceled for the rest of Wednesday.
