Two motorcyclists have been taken to hospital following two separate crashes on Norfolk's roads.

One man is currently fighting for his life at the Norfolk and Norwich University Hospital following a hit and run on the A146 Norwich to Lowestoft road near Loddon this morning.

Emergency services were called at 6.52am to reports that a motorcycle had crashed on the road close to the junctions with Stubbs Green Lane and High Bungay Road.

The motorcyclist was taken by ambulance to the Norfolk and Norwich University Hospital where his injuries, including a broken pelvis, are described as life-threatening.

It is now thought he was in collision with a white Fiat van, and a man, believed to be the driver, has been arrested on suspicion of failing to stop at the scene of a road traffic collision and is being questioned by officers at Bethel Street police station.

The road is still closed while accident investigators examine the scene, and motorists are being advised to avoid it for the rest of the day.

In the meantime traffic is being diverted through Loddon, causing major tailbacks through the town.

In a second incident at 8pm last night, a 33-year-old motorcyclist was taken to the James Paget University Hospital with head and pelvis injuries after his Suzuki 750cc motorcycle was in collision with a grey Mini Cooper.

The accident happened on the A149 with the junction with the B1152 at Repps with Bastwick.

Anyone with information, or who may have witnessed either collision is asked to call Norfolk police on 01953 42 42 42.
