Ref. 75759-53THE Environment Agency says it has tracked down the firm responsible for a fuel leak which polluted a Swindon river.

Up to 10,000 litres of red diesel poured into a tributary of the River Ray, by the Westlea Industrial Estate on Sunday.

Emma Cassidy from the Environment Agency said: "We believe we have found the source and stopped any further discharge.

"It is now part of an ongoing investigation, which may result in possible enforcement action against the company.

He added: "At this stage we can't release the name of the company."

Ms Cassidy said the leak had killed off hundreds of stickleback fish living in the river.

Efforts are continuing to clean up the river but 4,000 tonnes of diesel remains.

A moorhen that was rescued from the river by the Swindon Swan Sanctuary is said to be making good progress towards recovery.

Roger and Sue Hulbert, which runs the sanctuary from their home in Shrivenham Road, feared the bird would not make it after rescuing it from the spill.

But Sue said the stricken bird had started to feed itself and would soon be well enough to return back to its natural habitat.
