HAMILTON HEIGHTS, Manhattan (PIX11) — A man was caught on video hitting a stranger in the back of the head with an orange baseball bat in Manhattan, police said.

The unprovoked attack happened while the 47-year-old man was walking by 1770 Amsterdam Ave. in Hamilton Heights at around 8 a.m. Tuesday, police said. The victim suffered some bruising and a head laceration. He was taken to the hospital in stable condition, police said.

The NYPD surveillance video shows the suspect pulling the bat from his pants before taking a big swing at the back of the victim’s head. The man in the red jacket falls on the sidewalk and rolls on the ground a few times as the suspect walks away. The assailant walks back to the victim and threatens to hit him again with the bat, the video shows. The victim then sits up and exchanges words with the suspect as the assailant walks away, according to the footage.

The victim and the attacker did not know each other, police said.
