Police are asking for the public's help as they search for a serial groper in Queens.
The New York City Police Department says all four incidents took place within a two-hour window Tuesday morning in Astoria and Woodside.
Investigators say each time the man attempted to talk to the victims before touching their backsides over their clothing.
The victims ranged from 14 to 25 years old.
