Police are looking for a man they said swung a metal pipe into another man's face on the subway in Manhattan on Saturday night, fracturing the victim's skull.

It happened around 11:15 p.m. on a southbound 2 train near the Chambers Street station.

The city police department released video showing 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, the alleged attacker puts the pipe on a hand truck and starts wheeling away. The other man appears to hold his hand to his head.

The 59-year-old victim was transported to a local hospital in serious but stable condition. Police said one of the man's eye sockets was also broken in the attack.

The attacker was described as being in his 20s, last seen wearing a black cap, a blue t-shirt, dark pants, and black shoes.
