VIDEO: Brooklyn bodega customer bashes stranger with beer bottle during random argument

A man buying a six-pack from a Brooklyn bodega was caught on video smashing one of the bottles over the head of a customer after the two strangers got into a quarrel, police said Sunday.

The attacker started arguing with a 63-year-old man hanging around in the deli on Rockaway Parkway near Farragut Road in Canarsie about 10 p.m. Sept. 1, cops said.

Surveillance video released by cops Sunday shows the victim tumbling out the door into torrential rain, his bare feet in the air. The furious assailant hurls a bottle at him while he’s down.

The victim suffered a cut on his head but declined medical treatment. His attacker ran off and has not been caught.

Cops are asking the public’s help tracking down the attacker. He has dreadlocks, a dark complexion and medium build and was wearing a gray T-shirt, black pants and black shoes.

Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.
