CCTV has been released after a man was knocked unconscious in a violent argument in a Newcastle supermarket.
The attack took place just after 10pm on Saturday, November 21, when two strangers got into a disagreement at the Aldi on Walker Road.
The two men were waiting in the queue at a till when the argument took place before one of the shoppers punched the other, knocking him unconscious.
Emergency services were called but when police officers arrived, the suspect had already fled the scene.
