The video footage from @999London is linked to a 'serious stabbing' which occured on the Greenwich Peninsula on Wednesday afternoon, leaving a man in hospital critically injured.

Four men can be seen swinging blades and other weapons at each other in the broad daylight attack as neighbours repeatedly scream for them to stop.

The brawlers fight with knives, machetes and a hammer during the horrfying south east London row.

The distressing footage was taken at around 4:20pm on June 2 on Barge Walker and Bessemer Place in North Greenwich, shortly before police and paramedics rushed to the scene.

The London Air Ambulance was called, and one man was rushed to hospital where he is critical.
