PHOENIX (AP) — A man shot three people Thursday in a computer room at a Phoenix community college, injuring two of them critically, authorities said. The shooter fled, but a man was arrested nearby.

The shooting at South Mountain Community College was part of a running dispute between the shooter and one of the victims, said Sgt. Andy Hill, a spokesman for the Phoenix Police Department.

"This was not a random shooter going around the campus shooting," Hill said.

Two of the injured people were struck by stray bullets, he said.
