Five punks attacked and robbed a delivery man in Brooklyn, police said Friday.

The 20-year-old man had just dropped off a pizza at 32 Walton Street in South Williamsburg at around 4:30 a.m. on Feb. 8th when he soon found himself surrounded, cops said.

Video shows two young-looking men approach the worker as he’s about to climb onto his e-bike and shove him off.

“If you don’t give us everything, we’re going to have to kill you,” one of the thugs threatened the 20-year-old, sources said.

One man then pushes him out of the way, towards another who flings him to the ground.

Two of the men wrestle with the 20-year-old as they try to get a hold of his property, before stabbing him with an unknown item in both legs during the tussle, police said.

The thugs made off with his cell phone, about $70, a jacket, a pizza, and the e-bike, cops said.

The suspects are still on the lam.

The victim was taken to NYC Health & Hospitals/Woodhull for his injuries. It is unclear what delivery company or restaurant he worked for.
