A Milford teen-ager was arrested and charged with first- and second-degree assault yesterday after he was accused of firing a BB gun at a school bus, slightly injuring a 10-year-old passenger.
Bill Toohey, a Baltimore County police spokesman, said the 10-year-old passenger and a 14-year-old boy - who was not on the bus - began arguing while the bus was stopped near Raleigh and Rockridge roads about 3:25 p.m.
The teen-ager, whose name police are withholding because he is a juvenile, is accused of firing the gun at the bus window, Toohey said. The 10-year-old, who was returning from Pikesville Middle School, was struck once in the lip. He was treated by his family physician, Toohey said.
The teen-ager, a student at Milford Mill Academy, later was arrested at his home in the 1400 block of Raleigh Road.
Baltimore County school officials are investigating.
