Police say a teenage girl is in juvenile hall facing serious charges after allegedly trying to run down a little boy on a bicycle last weekend after claiming he threw a water bottle at her Mercedes.  

A witness tells News10 the 17-year-old girl made a U-turn on Yellow Stone Lane in the Arden Arcade area after the bottle hit the car.

"He was trying to get away from her. She followed him and basically mowed him down," the witness said. 

Police say the girl's car hit the boy in the front yard of a nearby home, but a tree saved him from being crushed to death.  

Officers also say she showed no remorse for what happened and admitted she did it on purpose.
