Robert Hart, 26, who was attacked at Parklife Weekender protecting his girlfriend, has died four days after being punched in front of the main stage.

Greater Manchester Police are still appealing for witnesses, the attack happened around 9.15pm on Saturday, 7 June 2014, as the 26-year-old victim and his girlfriend were dancing in front of the Festival’s main stage when he was attacked by an unknown man.

The offender is described as a mixed race male, aged approximately 25 years old and around 6ft tall. He has a muscly build and short, curly, black hair which was shaved at the sides.

Det Insp Richard Eales: “Our immediate thoughts go out to Robert’s family and loved ones. We currently have specially trained officers with them to help through this terrible time.

“We believe a confrontation took place following an inflatable doll hitting Robert’s girlfriend.

“We are aware other assaults took place in the park that evening, but I am specifically appealing for witnesses who recall seeing the inflatable doll and the attack on Robert immediately thereafter.

“I am keen for those witnesses to come forward and other persons nearby who may have mobile phone footage of the attack or captured an image of the person responsible.”

Police have released an e-fit of the man who is believe to be responsible, if you recognise him please contact Greater Manchester Police.
