A rescue operation was under way yesterday after two ducks became covered in oil that was dumped in a village pond.

RSPCA officers were called to the pond at Old Buckenham, near Attleborough, after a can of what is believed to be engine oil was thrown in the water.

A charity spokesman said the ducks were in a “terrible state” and probably the worst-oiled birds its officers had seen.

She said that, once caught, the birds would be taken to the charity's wildlife centre at East Winch to be cleaned.

The pond is also home to fish and plants and has been described as a valued village amenity.

Local people said they were horrified by the “mindless stupidity” of those responsible.

Doug Baker, who lives nearby, said that improvement work was being carried out on the pond when the incident happened.

He said: “They couldn't be bothered to throw the oil in the bucket opposite where people put rubbish. They had to throw this plastic can or canister of oil into the water.

“The can was full of what looks like engine oil or sump. There is thick black tar all down one end of the pond. All the fish are at the other end and the ducks are covered in it. It is mindless stupidity. Where is the money going to come from to put this right?”

An Environment Agency spokesman said a worker was heading to the scene with absorbent pads and a boom.

She said: “People must dispose of oil responsibly and keep it well away from water. If you are not sure how to dispose of it, contact your local authority.”
