Officers from the Metropolitan Police Service's Roads and Transport Policing Command are appealing for information after a Transport for London Revenue Protection Inspector was assaulted on a bus in Islington.
As part of the appeal they are releasing an image of a man they would like to speak to in connection with the incident.
The incident occurred on Thursday, 17 September at around 17:50hrs, on board a route 73 bus travelling on Essex Road, Islington, when the victim, a 29-year-old man, was punched and kicked after being asking to check his ticket.
The victim received minor injuries, which did not require hospital treatment and the assault may have been more severe had his colleague not intervened.
The suspect is described as a light skinned black man, aged about 17 to 25 years of age. He was wearing a grey cap, with long afro hair tied in a ponytail.
Anyone with information is asked to contact Police Constable Neil Webb leading the investigation on 0203 0546712 or Crimestoppers anonymously on 0800 555 111 quoting ref 192860.
