Oil spill alert on River Bourne in Hampshire
Work is continuing to clean up an oil spill on a Hampshire river.
The Environment Agency said inflatable booms and absorbent pads were being used to contain the pollution on the River Bourne, north of Andover.
The agency was alerted at 03:00 BST and the spill has subsequently affected a 10km (six mile) stretch of river south of Hurstborne Tarrent.
The river is renowned for salmon fishing. The cause of the spill is being investigated.
Evidence of a "thin film" of oil was found at Bransbury, near Longparish.
A boom was put across the river north of Stockbridge to prevent pollution entering the River Test
The agency said no dead fish had been reported but advised people to keep themselves and their pets out of the water.
Manager Simon Moody said: "Environment Agency officers have been out since first light doing everything they can to minimise the impact on the environment."
