Three boys, one aged 12, have been arrested on suspicion of murder after a man was fatally injured outside a fast food restaurant in Greater Manchester.
The victim, aged in his 40s, died in hospital after the assault close to McDonald's in Warrington Street, Ashton-under-Lyne, on Wednesday night.
Three boys - the others aged 16 and 17 - were arrested over the weekend.

"Our investigation continues and I would urge anybody with information to please contact police."
