BROWNSVILLE, BROOKLYN — A man pulled out a gun and shouted "I'll blow your head off!" when a deli worker wouldn't allow him to buy Cheetos with a counterfeit $50 bill, police said.

The Cheetos fan dumped his purchases on the counter of Rockaway Fruits and Vegetables at 694 Rockaway Ave. around 7:15 a.m. on Dec. 31, police said. The deli worker refused to complete the sale — telling the would-be customer his $50 was counterfeit — and so the suspect pulled out his gun, said police.

"Try and do something," the man said, "and I'll blow your head off." He then grabbed his Cheetos and ran down Rockaway Avenue toward Dumont Avenue, according to police.

Police describe the suspect as 6-foot-tall man in his mid-20s, weighing about 180 pounds and sporting a beard. Anyone with information about this incident is asked to contact police.
