A man in a Spiderman mask robbed a Bronx bank. (FBI)

FORDHAM, the Bronx — This Spiderman mask-wearing bank robber is a menace.

A man donning a Spiderman mask held up a Bronx HSBC bank, the FBI said Saturday. He walked into the East Fordham Road bank on April 25 and threatened a teller with what he said was a bomb.

The man showed the teller a box and said a bomb was inside, FBI officials said. Surveillance video shows the man zipping up the mask to fully cover his face. He demanded money and fled with the cash around 12:50 p.m.

The man was also wearing a black coat and black sneakers with his mask, an FBI spokesperson said. He is about 5 feet 6 inches tall and weighs about 130 pounds.

The FBI is offering a reward of up to $5,000 for information leading to an arrest in this case.
