Witnesses sought over Parklife festival death
Police issue images of five more people who may have witnessed a man being fatally injured at Manchester's Parklife festival.
Robert Hart, 26, of Macclesfield, Cheshire, died in hospital four days after he was assaulted in Heaton Park at about 21:15 BST on 7 June.
He was attacked by a man before Snoop Dog was due to go on stage.
Greater Manchester Police said the five had been standing close to where Mr Hart was killed.
Det Ch Insp Phil Reade said: "One of these people could hold the key to unlocking this investigation without even knowing it."
Police have been able to identify 10 of the 12 people whose images were released on a BBC Crimewatch programme in June.
