It was reported at around 12.30am on Saturday, August 30 that the victim, a man in his 20s, was passing through crowds in front of Soho Bar on Concert Square in Liverpool City Centre when another man punched him in the face and two other men joined in the assault in an unprovoked attack.
The man sustained a broken jaw which required surgery.
CCTV and witness enquiries are ongoing to identify the suspects responsible, and detectives have issued images of three men they believe could assist with their investigation.
Detective Inspector Paula Jones said: “This was shocking and unprovoked assault where the victim sustained a broken jaw, and he is still recovering from the injury.
“People should be able to enjoy a night out without being subjected to any kind of violence or fear of being assaulted.
“I am appealing to the three men featured in the images, or anyone who recognises them to come forward. We believe they could hold information that could be vital to our continuing enquiries.
“I would urge anyone who witnessed the incident or has information which can help with our investigation to please contact us or call Crimestoppers anonymously.”
