Boise, ID -

Authorities in Boise are pursuing felony charges against a 15-year-old boy accused of pointing a BB gun at a school bus driver and a 10-year-old girl.

Police arrested the teen Monday after the young girl helped police identify the suspect.

Investigators say the boy was a passenger in a car when he pointed the firearm at the bus driver. A short time later the teen allegedly pointed the gun at the girl as the car was driving by.

Later at school, the girl called her mother, who then called police. The girl provided police with a description and officers ultimately found the car with the suspect and a black handgun -- which turned out to be a BB gun.

Boise Police Lt. Rob Gallas praised the 10-year-old for quick thinking.
