Police are looking for a suspect who slashed a man in the head after the victim tried to confront him for punching and beating a dog with a belt.
Investigators on Saturday released a surveillance video of two men who appear to be beating and mistreating two dogs on leashes.
A 32-year-old man was passing by the location on Staten Island on May 24 when he saw a man punching, kicking and beating a dog with a belt, police said.
The victim tried to intervene but the suspect pulled out a knife and slashed him above the eye, investigators said. Information about the extent of his injury wasn't available.
Detectives are looking to speak to the two men seen in the video.
Anyone with information about them is asked to call the NYPD Crime Stoppers Hotline at 1-800-577-TIPS.
