Wild video shows man punch fellow shopper in NYC Costco brawl over shopping cart

Wild video shows the moment a spat between two couples over a shopping cart turned to blows inside a Brooklyn Costco — with one injured man falling to the floor in the middle of an aisle.

The mayhem erupted around 3:50 p.m. Sunday inside the superstore on Third Avenue near 37th Street in Sunset Park, police said.

The viral footage — which has racked up more than 900,000 views since it was posted on X the same day — shows the couples bickering in the aisle over the cart. 

One couple begin to physically fight with a man wearing a white T-shirt and black pants as his gal pal yells, “Do not touch him! Do not push him!,” the clip shows.

At one point, the T-shirt-wearing man slugs his male rival on the side of the head and shoves his female partner out of the way, according to the clip. 

The man who took the punch falls to the floor, hitting his head on a shopping cart, police said. 

“Call the police!” the woman who was with the injured man yells in both English and Spanish. 

The victim was taken to NYU Langone Hospital-Brooklyn for treatment, police said. 

Meanwhile, his assailant fled, cops said.

Anyone with information on his whereabouts is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS (8477) or for Spanish, 1-888-57-PISTA (74782). The public can also submit their tips by logging onto the Crime Stoppers website at https://crimestoppers.nypdonline.org/, on X @NYPDTips.
