Two people were killed at the University of California in Los Angeles, shutting down the campus for two hours as officers in camouflage and tactical gear responded to reports of a shooting.
Los Angeles Police Chief Charlie Beck confirmed one man shot another and then himself in the engineering building and that police recovered a gun at the scene.
"There are no suspects outstanding and no continuing threat to UCLA's campus," Chief Beck told reporters without offering further details about the victims.
Police recovered what may turn out to be a suicide note, he added.
The shooting created a stir as around 200 police approached the scene fearing the shooter might still be active and university officials ordered the campus locked down.
President Barack Obama was briefed aboard Air Force One and he asked his team to keep him updated, White House spokesman Josh Earnest said.
After several tense hours, university officials announced classes would resume tomorrow.
UCLA, with more than 43,000 students, is in the Westwood section of Los Angeles and one of the more well-regarded schools in the University of California system, known for its successful sports program.
Los Angeles Mayor Eric Garcetti praised the people of UCLA for "extraordinary grace and calm" and lamented the violence at a place of learning.
"I am heartbroken by the sight of SWAT teams running down avenues normally filled with students, and angered by the fear that one person with a firearm can inflict on a community," Mr Garcetti said.
