PHILADELPHIA (CBS) — Police are trying to find a dirt bike rider wanted for a hit-and-run crash in North Philadelphia.

Surveillance video shows a 17-year-old boy riding a skateboard down Allegheny Avenue near Front Street late Sunday night. All of a sudden, a dirt bike rider doing wheelies comes flying down the road, running right into the boy.

Police say the teenage victim is in extremely critical condition.

If you recognize anything about the dirt bike rider, call the police.
