INVESTIGATORS from the Environment Agency have issued a notice to stop a Potteries-based firm from discharging industrial material after a cyanide leak in the River Trent.

Environment Agency officers have been on site at Red Industries in Burslem after tests showed the presence of cyanide at the sewer discharge point used by the company.

Now officers have served a Suspension Notice to prevent the firm from discharging any industrial effluent to the sewer system.

The issuing of the notice follows swift action by the Environment Agency in its ongoing investigation into the source of the cyanide pollution of the River Trent on Tuesday night.

David Hudson, Environment Manager said: "The pollution has killed thousands of fish on the River Trent, and caused a great deal of concern for many people. This sort of incident is unacceptable.

"Our investigation is continuing to ensure we can take firm action against those responsible."
