A new photograph has been issued by detectives hunting for the killer of a family man murdered in Sheffield city centre over a year ago.
Richard Ismail spent more than 12 months in hospital after being attacked on a night out in Barker’s Pool in November 2012.
Despite months of hospital care, Richard tragically died at the weekend.
The police investigation, which had initially been one of assault, has now become a murder inquiry.
Richard, aged 45, was attacked outside the Lloyds No 1 bar in Division Street, Sheffield, in the early hours of Remembrance Sunday November 11, 2011.
Known as Moody to his many friends, he spent months in a coma and was latterly being treated at a specialist brain injury rehabilitation centre in Stocksbridge, Sheffield.
The Star reported his death on Tuesday.
Today Detective Chief Inspector Natalie Shaw made a fresh appeal for witnesses.
“We appreciate this occurred over a year ago, “ she said. “But we are sure there are witnesses out there that haven’t yet come forward.
“People know who did this, and they need to have the courage to tell us what happened.
“Richard and his family deserve that at the very least.”
Police know Richard sustained a head injury during an altercation outside the bar.
A post mortem examination conducted on Monday evening this week established his death was connected to the injury he sustained during the assault.
He was rushed to hospital initially in a critical condition, and detectives closed the road - and temporarily the bar itself - in the initial few hours of the investigation.
Two men aged 19 and 24 were arrested last year and released on bail.
n Anyone with information about the incident, at around 12.30am on November 11, 2012, is urged to contact South Yorkshire Police on 101 quoting incident number 67 of the same date.
