NEW YORK (CBSNewYork) – Surveillance cameras in the Bronx caught a brutal assault and robbery of a delivery man by a violent group of attackers.

Police say the 36-year-old victim was making a delivery for Uber Eats when four men ambushed him and pushed the worker off his bike.

The group then punched the victim to the ground and allegedly threatened him with a knife before getting away with his electric bike and iPhone.

Police say the attack happened last month on Feb. 26 in the Mount Eden section near Edward L. Grant Highway.

Police believe the suspects are all in their late teens.
