A man suffered a fractured eye socket and will need surgery after a thug walked into a pub where he was drinking and punched him in the face.
Now police have released this image in the hope they can track down the attacker, who also punched the victim's friend.
It comes after the thug went up to a man sitting at a table in The Clipper pub in Dartford's high street and punched him in the face at just after midnight on February 9.
But as a friend of the victim stepped in he was also punched in the face.
It's thought the assault followed an argument on the dance floor between the attacker and his friends and some of the victim's friends.
The first victim - aged 33 and from Swanscombe - suffered a fractured eye socket. He will now need surgery to correct his vision.
The friend, who is 43 and from Aylesford, had a cut to his face.
The suspect is a white man in his early 20s. He is believed to be around 5ft 8ins tall and wore a dark blue polo-style T-shirt and dark trousers.
Investigating officer, DC Sasha Monck, said: "This was an unprovoked and violent assault on two men, one of whom suffered serious facial injuries and is experiencing ongoing issues as a result.
"This sort of behaviour will not be tolerated by Kent Police. I believe the man pictured may have information that could help with my investigation and I'd urge him or anybody who knows him to contact me."
