Robber in 'serious condition' after Oxford jewellery raid
A man is seriously ill in hospital after being grabbed by passers-by during a robbery in Oxford city centre.
He is believed to be one of two men wearing crash helmets who raided John Gowing Jewellers in the Covered Market at 09:15 GMT, said police.
The other man discarded his helmet and ran off before catching a bus.
South Central Ambulance Service said staff treated a man at the scene for a cardiac arrest and continued "life saving treatment" en route to hospital.
Det Supt Chris Ward, leading the investigation, said: "At this stage we believe that members of the public restrained one of the offenders, while the other ran away, leaving the Covered Market via Turl Street.
"As the man ran away, he discarded his helmet and some clothing we have subsequently recovered in Boar Street.
"It appears that the man has then got on a bus in the city centre and then got off in the area of St Clements."
Police are appealing for witnesses who saw the second man fleeing the scene.
They also want to speak to anyone who saw the two men pushing a motorbike towards the jewellers before the raid.
The man who escaped is described as white, and he was wearing a black and white T-shirt and blue jeans.
