NEW YORK (AP) -- Police say a New York City subway rider snapped a cell phone picture of an 18-year-old scratching graffiti on a train window, leading to the suspect's arrest.
Andrew Morello was arrested Friday on charges of making graffiti.
Police say a witness photographed Morello in the act Monday on an N train in Queens and sent the pictures to the city's tips hot line, which recently began accepting cell phone images and text messages.
The images were passed onto the Citywide Vandals Task Force, which tracks down graffiti writers.
Police say Morello is a known graffiti writer.
