Dramatic footage shows the moment a man managed to disarm a knife-wielding thug after being stabbed in the middle of a busy city street.
The pair can be seen wrestling on the ground along Slade Road, in Erdington, Birmingham - which previously made headlines for being "Britain's roughest street".
Shockingly, nobody does anything to help as pedestrians simply watch on and cars drive past as the terrifying scenes unfold.
The footage begins with the two men struggling on the ground while a huge blade can be seen being brandished and waved around in the air.
One of the men manages to disarm the other while an onlooker can be heard saying: "He's stabbing him up, he just took that knife about ten times you know."
A female witness then repeatedly shouts "call the police" until the fight comes to an abrupt end when one of the men gets up and casually walks away.
West Midlands Ambulance Service confirmed one male victim suffered "serious injuries" following the altercation last Tuesday evening (18/7).
A service spokesperson said: "We were called to reports of a stabbing at the junction of Kings Road and Slade Road at 7.50pm on Tuesday.
"One ambulance, a paramedic officer and a MERIT trauma doctor attended the scene.
"On arrival we discovered one patient, a man, who was treated for serious injuries before being taken to hospital."
A West Midlands Police spokesperson added: "We're investigating after a man was stabbed near Slade Road, Erdington, at around 7.40pm on Tuesday (18 July).
"A man was taken to hospital with injuries which were not life-threatening. We're carrying out enquiries in the area.
"We're aware of a video which was shared on social media at the weekend, and we would ask anyone with information to contact us to assist our investigation.
"Contact us via Live Chat on our website, or by calling 101, and quote crime reference number 20/624953/23."
The disturbing footage has since been viewed more than 11,000 times after being uploaded by the Birmz Is Grime blog.
One web user asked: "Am I the only person who would have got out their car and helped? What is going on with humanity??"
Another commented: "I liturally [sic] can not believe others stood there watching instead helping."
A third added: "Imagine standing there and potentially filming someone get murdered."
Another wrote: "And everyone is watching as if it is a normal daily routine!! What is happening to humanity."
