(CNN) - A gunman opened fired Thursday at Seattle Pacific University, killing one person and wounding three before a student tackled him, Seattle police said.
The gunman was reloading a shotgun when the student, working as a building monitor, knocked him down, Police Capt. Chris Fowler told reporters.
"Once on the ground, other students jumped on top of them and subdued the shooter," he said.
The suspect, whose identity was not immediately released, is in custody, police said.
The shooting began inside the foyer of Otto Miller Hall, which houses the university's science, math and engineering departments, when the gunman confronted three people and shot them, Fowler said.
