Eighty swans have been removed from the River Thames due to a mystery oil spill which is baffling authorities. Thames Water was called out at 10:30pm last night to the stretch of river between Windsor Bridge and Eton Bridge.
The Environment Agency, with assistance from Thames Water, is investigating the source of the spillage but said it is 'quite unlikely' they will find the source due to most of the oil having dispersed leaving just isolated pockets.
Bob Lang, a volunteer at the charity Swan Lifeline, said: 'I've seen it before but nothing like this. I've been coming for about 20 years.' Around 20 volunteers have been working to remove the swans from the river and so far about 80 of them have been lifted off - with more work to do, Mr Lang said.
