Thames Water has dropped plans to appeal after it was fined £60,000 for allowing raw sewage to pollute a stream and river.

The water company was fined and ordered to pay £4,350 legal costs at Oxford Crown Court last month after admitting failing to stop raw sewage from leaking into the Cholsey Brook and River Thames, near Wallingford.

Workers ignored a series of alarms warning about the leak on September 7, 2003, which happened after a filter system became blocked.

The leak killed 12,000 fish. A spokesman for the company said they had considered appealing against the level of the fine.

"We are no longer pursuing our idea of appealing against the ruling," she said.
