The mum of a man who died after being punched in an unprovoked attack at the Parklife Festival three years ago has made a fresh appeal for witnesses to come forward.
Robert Hart died days after he was punched unconscious at Heaton Park on June 7, 2014.
He had been arguing with a festival goer who was repeatedly striking his girlfriend with an inflatable doll.
He died in hospital after suffering a severe bleed to the brain.
Despite numerous police and press appeals for witnesses to come forward the man who carried out the “unprovoked attack” has never been caught.
Now Robert's mum Elaine Hart said she and Robert’s friends and family still want justice.
She said: “The man who killed my son went somewhere that night, he walked away and he woke up somewhere the next morning.
“Someone knows where and who he is. Someone must have spoken to him.
“He is guilty of taking our Robert’s life in an unprovoked attack.”
Describing her son, 68-year-old Elaine said he was the “perfect gentleman”.
She added: “We will always be devastated at the loss of Rob.
“He was one of four children, two girls and two boys, who were all the best of friends.
“We still don’t understand why this happened to such a gentleman, he was so funny and well liked by everyone, no-one had a bad word to say about him.
“In our heads we will never come to terms with why there was a need for such a forceful punch.
“Robert wasn’t aggressive and the attack was totally unprovoked, he had his hands by his side.”
Elaine, who lives in Macclesfield, said she visits her son’s grave every week to leave flowers.
She added: “I go there and I say to him ‘you shouldn’t be here son, you should be living your life and enjoying yourself’.
“He could still have been with us and we will never be able to get over it.”
Robert had been working at the Barclays call centre in Wavertree, before his death.
His mum said now is the time for people to tell the “truth”.
She added: “To this date his killer has not been caught. He is out there and I just want people to tell the truth.
“If anyone has any information, any at all - they may have been in a pub and overheard something - or not think what they have to say is important enough, it is.
“Police will look into any fresh information.
“A girl pulled my son’s attacker away that night and the two walked away - they didn’t just disappear, someone must know something.”
