CCTV has been released of a man swinging a knife during an attack involving seven men in East London.
The clash between two groups in Bow at around 7.40pm on July 25 left a 21-year-old man with knife wounds to his head and left arm.
He was taken to a London hospital where he was treated and later discharged.
Detectives have released footage to help trace four men of Somali origin who allegedly attacked a group of three Asian men outside the Original Taste fast food shop.
The video shows the knifeman wielding a weapon in his left hand, slashing the victim before running off.
He was wearing a blue or grey tracksuit with white writing across the chest and had his hood up.
Another suspect, who was also caught on camera, was wearing a dark grey hooded top and a black Puffa jacket.
There were two remaining suspects - one, who was not in the clip, wore dark clothes with his hood up. His jumper featured a white drawstring and white stitching.
There was no clear image of the fourth suspect, who was wearing shorts, black trainers and a white hooded jacket with blue-and-white stripes.
Anyone with any information is asked to contact police on 101 or Crimestoppers anonymously on 0800 555 111.
