Teenage gang kill man in vicious attack.
Mi Gao Huang Chen, aged 41, was battered to death with a spade, tree branch and metal pipes by the gang which, according to residents, has plagued their community with anti-social behaviour.
Mr Huang Chen, known to his customers as Michael, ran Superb Hut takeaway in a shopping precinct in the Scholes area of Wigan, Greater Manchester.
He was set upon by the gang at 11.30pm last Saturday in a savage 15-minute attack, police said.
He suffered massive head injuries and was left in a coma as doctors fought to save his life. He died in Hope Hospital, Salford, on Thursday without regaining consciousness.
Police initially arrested 15 teenagers on suspicion of assault and violent disorder. All have been bailed.
Yesterday detectives arrested four more youngsters on suspicion of murder, they include a boy and a girl, both aged 14, and a boy and a girl both aged 15.
They are now being questioned by murder squad detectives.
The killing has prompted claims that it shows teenagers 'out of control' with the criminal justice system in 'crisis'.
Detective Chief Inspector Steve Crimmins, leading the investigation, said: 'It is quite frightening really, it was a frenzied attack.
'It was horrific and sickening.
'There have been on going problems in the area. There was a heightened police presence prior to the incident.
'There's been general nuisance you associate with large groups of youths, in essence rowdiness and criminal damage. For some reason it has escalated out of all proportion and a man has lost his life.
'This type of behaviour will not be tolerated and the attack last weekend is unacceptable
