More than 100 swans rescued from an oil spill in the River Thames in Windsor have been released back into their habitat.
Volunteers from Eton charity Swan Lifeline in Cuckoo Weir Island took the 120 swans back to the water this morning.
They had been cleaned with washing-up liquid and cared for since Saturday morning after they were covered up to their necks in oil.
The Environment Agency said the cause of the spill is still being investigated, but it is believed it could be from illegal fly-tipping.
A spokeswoman said yesterday: "We are still investigating the source of the oil and therefore we cannot confirm where it originated.
"However, owing to the nature of the incident and the fact the oil dispersed fairly quickly it is likely to have been illegally disposed down a surface water drain."
Concerns have been raised after a man in Windsor was hit by human waste from an aeroplane whilst in his garden.
