Police in New York City are searching for three men behind a brutal attack in the Bronx and left their victim unconscious.

The NYPD released new surveillance video Sunday of the violent beating from earlier this month. Officials say a 34-year-old man was ambushed around 9 a.m. Aug. 4 on Prospect Avenue.

The video appears to show the three suspects approach the victim and shortly after begin attacking him.
