A quartet of robbers attacked a food deliveryman in the Bronx, whacking him in the head and running off with someone’s dinner, according to police, who released footage of the incident on Wednesday.

In the footage, the 47-year-old victim is seen walking with his bike when the foursome — all dressed in hoodies — approach him and block his path at 1821 University Ave. in Morris Heights around 7:30 p.m. Dec. 28, according to cops and the video.

The victim continues walking, but one of the suspects holds the bike’s handlebars, preventing him from moving. One of the attackers sucker-punches him in the back of the head, the video shows.

One of the attackers grabs the bag of food, and the group runs off down Morton Avenue, according to video and police.

The victim refused medical attention, police added.
