A plumber was attacked in the doorway of a customer's house by a violent passer-by demanding an early-hours lift from the tradesman.
This CCTV image of the suspected thug has been released by police in east London investigating the attack.
The 46 year-old victim was repeatedly punched in the face and had two windows of his vehicle smashed during the 2am confrontation.
On Sunday May 1, last year the plumber was sitting in his vehicle, which was parked in Findon Gardens, Rainham.
He was approached by a man who opened the passenger side door and asked to be taken to an address.
The victim explained that he was not a taxi driver and refused to give the male a lift.
The suspect then became aggressive and the victim, fearing for his safety, left his car to go inside the customer's address.
The victim entered the customer's address but the suspect pursued him and forced his foot in the door preventing it from being shut.
The suspect then assaulted the victim by striking him a number of times in the face before fleeing.
As he passed the victim's car, he smashed two windows before making off in the direction of Wennington Road.
The suspect is described as white, 5ft 8ins tall of slim build.
He was wearing a blue baseball cap, light grey/dark coloured hooded top underneath, black gloves, dark coloured trousers and dark coloured trainers.
He was also seen to carry a black man bag over his shoulder.
Police are keen to hear from anyone who may recognise the man shown on CCTV or who witnessed the incident.
Anyone with any information is asked to contact Detective Constable Raheel Sarwar from Havering Police on 01708 779155 or call Crimestoppers anonymously on 0800 555 111.
