A man who was seriously assaulted at the Parklife Festival in Mancester has sadly died and police have broadened their search for a man they would like to question.
At around 9.15pm on Saturday 7th June 2014, 26-year-old Robert Hart and his girlfriend were in front of the Festival's main stage when he was attacked by an unknown man.
Robert was punched to the ground unconscious and was given CPR at the scene by two off-duty medical personnel.
He sadly died yesterday in hospital.
The offender is described as a mixed race male, aged in his late 20's and around 6ft 1 tall. He has a muscular build and short, dark hair which was shaved at the sides. He was also wearing shorts and a blue, bomber-style jacket with the letter 'A' in white on the front.
Police have also issued an efit.
Detective Inspector 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 are still in the early stages of this investigation, however several witnesses have assisted us with vital information concerning the description of the offender. 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.
"Finally, if you are the man responsible or were with him that evening, please come forward."
