The two were believed to have roared up outside a covered shopping centre in Oxford on a motorcycle. They then ran into the arcade where they smashed glass in John Gowing jewellery store.


Sources said that moments after confronting the staff - one of who managed to dial 999 to alert the police - the older of the two raiders clutched his chest and collapsed unconscious to the shop floor.

The other man ran away from the shop, empty-handed. He left his accomplice behind, along with a black and green motorcycle which was lying on the ground.

A spokesman for the South Central Ambulance Service said the man had suffered a full cardiac arrest, causing his heart to stop beating.

'The ambulance service was called by the police who said that there was an "unresponsive male" on the floor of John Gowing jewellers' store in the covered market,' said spokesman James Keating-Wilkes.

'We sent a rapid response vehicle and a double manned ambulance to the scene and carried out CPR on the patient, who was aged about 40 years.

He said: 'He was still being resuscitated as he was stretchered on the way to the ambulance.

'He was a big bloke with a tattoo. We have heard he may have had a heart attack, maybe as he was being wrestled to the ground.
