A man who suffered horrific injuries when he was knocked unconscious during a night out has made a renewed appeal for help tracing his attacker.
The 36-year-old was left with a shattered cheekbone and eye socket and a dislocated jaw after the apparently motiveless attack in Belvoir Street, Leicester city centre.
An appeal in the Leicester Mercury in February did result in a number of names being passed to police.
However, detectives say they are keen to hear from more potential witnesses or people who believe they know the attacker's identity.
The victim, who has asked not to be named, was walking along Belvoir Street when he accidentally brushed shoulders with his attacker.
As he turned to apologise, the stranger punched him in the face without warning. The single blow knocked him unconscious.
"That single punch smashed my left cheekbone, broke my eye socket and dislodged my jaw," he said.
"The physical affects of the assault are starting to get better, but I still have that sense that justice needs to be done.
"The only way that is going to happen is if this man is caught. I don't think I'll be able to settle until that happens.
"It's a few months since it happened but I'm still having trouble sleeping – and when I do get to sleep I still have nightmares about it.
"I even went to the place in Belvoir Street where the attack happened because I thought it might help me in some way to get over it.
"I don't go out at night any more, so I went during the day. I'm not sure if it did any good or not. I'll have to wait and see."
The victim has released a photograph showing his injured face two days after the attack, which happened at 3.25am on Sunday, December 16, near the junction with Bowling Green Street.
The victim and his wife spoke to the Leicester Mercury in February in their first appeal for help trace the thug.
His wife said then: "I don't think any words can describe how I felt when I got to the hospital and saw what this man had done to my husband.
"I've seen the effect it's had on him. He will sit up in bed in the night with a jolt because he is still having nightmares about it.
"What makes it worse is that the person who did this to him has not been caught."
Police have released a CCTV image of a man they wish to speak to regarding the assault.
Detective Constable Andy Spence, of the force's serious crime team, said: "This is not going to go away until we trace the person who did this to this man.
"The victim needs this man to be caught so he can move on with his life.
"I would still appeal to people to come forward with names. Even if they are not sure, we will investigate those people and will rule them out if necessary."
The suspect is white, about 5ft 10in and in his mid-20s to mid-30s.
He has short, dark, spiky hair and was wearing a long-sleeved dark top, jeans and white trainers.
