An ambulance has been left stuck in an Oxford street for more than 15 minutes this afternoon after it was blocked by two cars.

The ambulance was picking up a middle aged man who had suffered a knee injury after falling off a bike in Lake Street, but was prevented from leaving by two cars parked by the road's health centre.

South Central Ambulance Service spokesman David Gallagher said the police had been called to try and find the vehicle owners.
