A Jewish man was attacked inside a lower Manhattan Duane Reade store when an innocent bumping erupted into a full-blown hate crime, police said Saturday.

The Tuesday morning beating comes as antisemitic incidents across the city have skyrocketed while the Israeli-Hamas conflict in Gaza continues.

The 66-year-old victim was leaving the Duane Reade on John St. near Broadway about 9:30 a.m. when he accidentally bumped into a 40-year-old man in a purple and black North Face jacket.

“F—— Jew!” the outraged stranger said as he turned around and punched the victim in the head, cops said.

The suspect was last seen wearing a purple and black North Face jacket, a yellow polo shirt and dark pants. (DCPI) The victim suffered a head injury in the split-second attack but refused medical attention.

His attacker left the store and remained at large Saturday. Members of the New York Police Department Hate Crimes Task Force are investigating the incident.

Tuesday’s attack was just one of a handful of antisemitic crimes to occur this week as Jews across New York celebrated the beginning of Hanukkah.
