Authorities say a driver trying to make a getaway sped down a busy New York City sidewalk, hitting a 9-year-old boy.

Video shows Brooklyn shopkeepers running after the car and throwing trash cans, trying to stop the driver, as pedestrians flee. The child's injuries were not serious.

WABC (http://7ny.tv/20JNLoP ) says it started around 4 p.m. Thursday when two men went into several stores trying to use a $20 bill that appeared to be counterfeit.

A pharmacy worker called police. The suspects tried to drive away but were blocked by rush-hour traffic. That's when they went onto the sidewalk.

One person is in police custody and a second was being sought.
