Scott High School was locked down Monday morning and SWAT team officers were called in.
Toledo police spokesman Lt. Mark King says the student had a pellet gun that looked like a handgun. He was taken into custody after officers fired a bean bag round at his feet.
No other shots were fired and no one was hurt. Negotiators talked to the boy during a short standoff, but officials say he didn't give a reason for bringing the gun to school.
Police got the call at about 9:30 a.m. There were no details about the boy's movements at the school before the standoff.
