NEW YORK (CBSNewYork) — The NYPD is looking for a suspect who attacked a man outside a Queens deli.

Police on Sunday released surveillance video of the incident at 31st Street and 38th Avenue in Astoria last month.

Investigators say a fight over whether the deli was open turned violent, when the suspect pulled out a knife.

The 60-year-old victim tried to defend himself, but ended up getting slashed in the head and arm, police said, adding the suspect also stole the victim’s slippers.
