A Chinese takeaway owner allegedly attacked by a gang of youths died from head injuries, a forensic pathologist has told a court.
Mi Gao Huang Chen died in hospital five days after the attack
Dr Philip Lumb gave his evidence at Liverpool Crown Court via video link from Australia, where he is on holiday.
Mi Gao Huang Chen, 41 and known as Michael, had suffered a fractured skull, facial injuries and bruising.
Five boys and a girl, all aged 15 and 16, are charged with carrying out the murder in April in Wigan.
Two of the boys pleaded guilty to murder. The other four have pleaded not guilty murder.
Two of the boys have admitted manslaughter but their plea has not been accepted by the court. None can be named.
The court heard Mr Chen was attacked by a gang of teenagers armed with wooden implements outside his Superb Hut takeaway in Scholes, Wigan.
Dr Lumb said: "He had a fracture at the back of his head from which cracks came towards the centre of the skull near the top of the brain stem and a fracture by his left ear extending to by his left eye socket."
His left jaw had been broken and his bleeding had crushed areas of his brain.
He said the cause of death was multiple blows to the head with a variety of blunt objects, kicks, punches and stamps.
Mr Chen died five days later in hospital.
The case continues.
