The NYPD is looking for a suspect who tossed a Molotov cocktail inside a mini-mart in Brooklyn, injuring a store clerk.

It occurred at a 24-hour store on Fort Hamilton Parkway just before 2 a.m. Wednesday.

Police say the suspect had argued with the clerk inside the store about an hour before the attack.

They released a surveillance tape showing a man in a hoodie lighting a bottle on fire and throwing it inside. It set off an explosion in one of the aisles. Witnesses say the clerk's hair and jacket caught on fire.

A co-worker used buckets of water to put out the flames.

The clerk was not seriously hurt.

Police ask anyone with information about the incident to call Crime Stoppers at 1-800-577-TIPS
