The images were taken shortly before the attack in Charterhouse Street at 3am on April 1.

The victim, 22-year-old Callum Wade from Maidenhead, suffered several facial fractures during the unprovoked assault.

He has permanent damage to his retina after he was punched and kicked to the ground by four men.

One of two friends Callum was out with was also assaulted but not seriously injured.

Police now want to speak to the three men in the images they have released, to try and trace the culprits.

Det Const Mark Pinder who is leading the investigation, said: “This was a violent assault which appears to have been launched with no provocation and has left Callum with injuries that will affect him for the rest of his life.

“The level of violence used was shocking and those who carried it out need to be traced before they commit a similar offence.”
