An investigation has been launched after tonnes of hospital waste was dumped at an old airfield in Suffolk, the Environment Agency said.

Hundreds of yellow bags filled with blood, excrement, dressings and used nappies were found in the Hulver Road area, near Beccles. A spokeswoman said the three-and-a-half tonnes of waste will be disposed of by a specialist company at a treatment plant.

Motorists have been advised to steer clear of the site while it is cleared.

“We want drivers to stay away from the area for obvious health and safety reasons until this terrible fly-tip has been cleared,” said Environment Agency spokesman Marcus Sibley.

“Hospitals should ensure that the companies they employ to take away their waste is properly registered to do so.”
