A man was attacked and robbed by three men in Brooklyn, police say.

The incident happened on Feb. 28 near 25th Avenue and Avenue V around 5 p.m. 

Police say one of the three men approached the 27-year-old victim and told him he had a knife.

After ordering the man to hand over his cellphone, police say the suspect told him his accomplice was behind him with a gun.

The two men ordered the victim to follow them inside of a 30th Avenue building where they were joined by the third suspect.

Once on the 4th floor of the building, police say the two suspects displayed a knife and a gun before placing the 27-year-old man in a chokehold while the third suspect went through his pockets.

The suspects got away with $160, three credit cards, a cellphone and headphones.

Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
