Police in the American city of Seattle have praised the bravery of a student for disarming gunmen who had killed one person and wounded three others. The student overcame the gunman on the campus of Seattle Pacific University as he tried to reload, police said. Pepper spray was used to subdue the attacker. Police said the actions of the student, and others who came to his aid, prevented a more serious tragedy. The gunman, who was believed to have been acting alone, was arrested. He is reported to have been carrying a shotgun and a handgun and opened fire after walking into the hallway of the university. "But for the great response at Seattle Pacific University(SPU)this incident might have been much more tragic," Seattle police spokesman Paul McDonagh told a news conference. Seattle Pacific University President Daniel Martin told the Seattle Times that the students who overpowered the gunman "acted without regard to their own safety on behalf of others". "We are a community and we care for others," Mr. Martin was quoted as saying. "Those that were involved did just that." He said that students and university personnel have procedures in place for when a shooting occurs, which was one reason why the gunman was subdued so quickly. Hospital officials in the Washington state city said the person killed was a man in his 20s. A woman is also in a very serious condition with a gunshot wound to her upper body.
