An injured worker was airlifted from a windfarm sub-station off the north Norfolk coast after a fall this afternoon.

A rescue helicopter from RAF Wattisham lowered a stretcher to the helideck on top of the Sheringham Shoal sub-station, about five-and-a-half miles off Cromer, and winched the man aboard.

He was taken to the Norfolk and Norwich University Hospital suffering from back injuries.

Cromer Lifeboat, which was on exercise and standing by at the Sheringham Carnival raft race at the time, was called to the sub-station at 1.20pm.

Coxswain John Davies said they had handed over their entonox pain relief to a paramedic on the sub-station who administered it to the injured man while waiting for the helicopter.

Workers are currently erecting 88 turbines as part of the wind-farm project, 10 to 15 miles off the coast, north of Sheringham.
