ANCHORAGE -

Alaska State Troopers say a 12-year-old boy has been arrested after he shot at a 13-year-old girl with a BB gun at a school gymnasium in the northern Alaska village of Ambler.
    
The girl was struck in the leg.
    
Troopers say the boy took the gun to the school Saturday night and shot at security cameras.
    
According to troopers, the boy then shot at the girl, who ducked for cover behind an entrance door.
    
Troopers say one shot struck the girl in the leg and another BB hit the door glass, which prevented the girl from being hit in the face.
    
The boy was arrested and taken to the Nome youth facility.
    
Ambler is a village of about 260 people located 138 miles northeast of Kotzebue.
