Police are looking for a group of about 12 people accused of viciously beating a paradegoer on Eastern Parkway in Crown Heights.
The NYPD says during the West Indian American Day Parade on Labor Day, a 44-year-old man was punched, kicked and slashed by a group of people. He was also robbed of his chains, wallet, phone and car keys.
The victim was taken to the hospital by private means.
The suspects fled the scene and have not yet been found.
Police say the attack was unprovoked and that a knife was used in the robbery.
Officials had announced 13 checkpoints along the parade route to ensure paradegoers were not bringing in any weapons.
Anyone with information is asked to contact the NYPD Crime Stoppers or the 77th Precinct.
