Deli clerk burned in gruesome Molotov attack

Stunning video shows a deranged firebug throwing a Molotov cocktail into a Brooklyn deli — and setting the clerk on fire, police said.

The suspect walked into the 24-hour MiniMart on Fort Hamilton Parkway, near 39th street around 1 a.m. and fought with the clerk about store credit before returning an hour later, cops added.

Security cameras caught him lighting the home-made explosive and hurling into the store with such force that he fell to the ground as he turned to run away.

The inferno set the 34-year-old clerk’s hair and jacket on fire, according to police. The victim miraculously escaped serious injury, authorities said.

The suspect is believed to be in his 30s, about 5-foot-8 and was last seen wearing sunglasses and a dark hoodie, police said.
