An oil slick which has affected hundreds of sea birds on the East Anglian coast is now threatening wildlife at the Lincolnshire resort of Cleethorpes.

A team of council workers is working to clear the oil from the sea front.

The source of the oil is unknown, although it is thought it may have leaked from an old wreck on the seabed.

Already one bird has died off Cleethorpes and a seal has had to be rescued.

High tide

Andy Smith from North East Lincolnshire Council said: "The oil at the moment is in very small deposits.

"It is being washed ashore and is being deposited at high tide.

"The oil is not the liquid sort but in small nodules so that should limit the impact."

Further down the coast, more than 600 oiled birds have been collected on the Norfolk and Suffolk coasts.

Guillemots, razorbills, great crested grebes and red-throated divers have mainly been affected by the slick.
