A NIGHT-TIME surveillance operation led to a swoop on two Worcestershire men pouring diseased fish into a pool.

Mike Giles and Paul Raymond Evans were caught when Environment Agency officers watched them pour diseased carp into a pool at the Yewtree Caravan Park, near Bewdley, on June 16.

Neither Giles, of The Plough Inn, Cleobury Road, Rock, or Evans, of Quarry Cottages, Rock, had a permit for stocking the pool with fish, Kidderminster Magistrates' Court heard.

A sample of the carp found they were infected with a parasite that could infect fish stocks.

The pair pleaded guilty to two charges of stocking fish without consent. Giles was ordered to pay a £500 fine and costs of £1,398.39. Evans was fined £150 and ordered to pay costs of £1,398.39.
