A takeaway customer was stabbed in the chest in broad daylight after an alleged dispute over a £4 cheeseburger.
Footage filmed at the scene of the incident in Scot Lane, Doncaster, South Yorkshire, shows a man wearing a white t-shirt and grey legging who comes charging out of a city centre takeaway.
He can be seen holding a pink plastic chair, which initially he appears to be using as a makeshift shield.
He hurls the plastic chair at the suspect, who then slashes him with a knife.
At some point, the suspect’s friends appear to intervene to calm him down and lead him away.
They also lead the injured man to the side of the street where he slumps down with his back against a shop doorway.
Shoppers are seen walking past, barely glancing at what is happening.
Cops were called to the scene at 4.40pm on Thursday after stunned bystanders raised the alarm and two men were later arrested.
South Yorkshire Police said the victim, in his 20s, suffered a stab wound to the chest and was taken to hospital, but his injuries are not life-threatening.
Posts on social media claimed the violence flared following an argument over a £4 cheeseburger.
Passerby Lee Stevens said: “From what I’ve gathered, some lad went into the takeaway for food.
“Something kicked off. He threw a chair at someone and then he got stabbed. I came out of the pub just after he got stabbed.”
Other people who were there claimed the row had broken out over a £4 cheeseburger.
Mr Stevens, who was hailed a hero on social media for having saved the victim’s life, added: “The guy that got stabbed is in Sheffield hospital and is fine. I did my best to make sure he didn’t bleed out. He’s okay.”
South Yorkshire Police said: “The victim, a man in his 20s, was taken to hospital with a stab wound to the chest. His injuries are not life-threatening.
“Two men, aged 38 and 23, have been arrested on suspicion of GBH. They remain in police custody at this time. Enquiries are ongoing.”
