The New York City Police Department says that a man accused of bashing a subway rider in the face with a metal pipe in Manhattan Saturday night has been arrested.

The unidentified 35-year-old was arrested late Sunday night at his home based on an anonymous tip that came in through Crime Stoppers.

Police say it's unclear what sparked the argument, but say that the suspect was panhandling on the train before the assault.

Video released by the NYPD appears to show the two men seated as one gestures at the other, then stands up and gets into a swinging stance before the video stops. In an apparently later section of video, he puts the pipe on a hand truck and starts wheeling away. The other man appears to hold a hand to his head.

The 59-year-old victim was hospitalized, but was expected to be OK.
