Police have released CCTV footage in a bid to track down the men responsible for an unprovoked attack outside an East Ham pub.

It follows an assault outside the Denmark Arms, in High Street North, that left the 34-year-old victim with a broken cheekbone.

He was standing outside on January 17 at around 12.20am when he was approached by a group of three men, aged between 20 and 40.

One of the gang (pictured) punched the victim twice in the face, causing him to fall to the floor, where he was kicked by the rest of the group.

The suspects then made off along High Street North and St John’s Road.

The man police believe threw the punch is believed to be in his mid twenties and of stocky build.

He was wearing a black Adidas jacket with a red motif on the left breast, a t-shirt, blue jeans and white trainers.

Det Con Grant Stevens said: “We believe this was an unprovoked attack and I would like to speak to anyone who may have seen or knows anything that may assist our enquiries.”

Anyone with any information is urged to contact the Newham Violent Crime Unit on 020 7275 5851 or Crimestoppers anonymously on 0800 555 111.
