SAN BERNARDINO, Calif. -  

Campus police at California State University San Bernardino shot and killed a graduate student following an altercation Saturday night, authorities said.

Police said officers responded to University Village, an off-campus student dormitory, regarding a disturbance involving Bartholomew Williams, 38.

Williams became aggressive and an altercation with officers followed in the hallway of the dorm, the college said in a statement. Officers then fired their weapons because they feared for their lives, police said.

Williams died at the scene.

One officer was taken to a hospital with non-life threatening injury.

Williams was majoring in educational instructional technology, and started at the school in the summer of 2011, police spokesman Sid Robinson said.
