A 'devastating' cyanide spill killed an estimated 2,000 fish in a pond, forcing the authorities to 'seal off' the area.
Toxic liquid poured into the pond after it spilled out of a ruptured tank at a nearby industrial estate in Heanor, Derbyshire, a fishing club said.
The poisonous chemical flowed down the road and into a drain before reaching Adam's Pond at Shipley Country Park.
