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

The 20-year-old man had just dropped off a pizza at 32 Walton St. in South Williamsburg around 4:30 a.m. Feb. 8 when he 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 pushes him out of the way, toward another, who flings him to the ground.

Two of the men wrestle with the 20-year-old as they try to get 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 cellphone, about $70, a jacket, a pizza, and the e-bike, cops said.

The suspects are still on the loose.

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