Wiltshire Police are appealing for information after an 18-year-old man was assaulted on Regent Street, Swindon.
The incident happened around 5am on Saturday 30 July 2016.
Wiltshire police would like to speak to three males in the attached CCTV images in relation to this assault.
The victim, who is from Swindon, received injuries to his face and was treated at the Great Western Hospital.
Det Con Sarah Munday said: “We would also like to speak to another man who was seen walking with the injured man up Regent Street, in the direction of Regent Circus, after the incident. If that was you, please come forward.
“Many people were out at this particular time of the morning due to the local night clubs closing, so someone must have seen something.
“If you recognise any of the three men in the images or heard or saw anything suspicious in this area at this time please contact me at Swindon CID.”
We are appealing for anyone who may have witnessed the assault or with any information to call DC 2388 Sarah Munday at Swindon CID on 01793 267013 or anonymously via Crimestoppers on 0800 555 111.
