This is the man detectives would like to speak to after a 43-year-old suffered a fractured jaw during an unprovoked attack in Brick Lane.
Officers from Tower Hamlets Police have released a CCTV still of the suspect in a first-year anniversary appeal to trace him.
The victim of the attack was punched in the face by a man who bumped into him as he left a shop near the junction of Hanbury Street, on November 1 last year at around 9pm.
His attacker then walked off.
Several men were arrested but later released with no further action.
If you know the man pictured you should call Tower Hamlets Police on 101 or Crimestoppers anonymously on 0800 555 111.
