Old cars, electrical goods and household and builder's materials were found dumped in Denham in a "major" incident of fly-tipping. 

Bucks County Council's enforcement officers have been sifting through the mass of rubbish that has been dumped under the A40 viaduct near Uxbridge in April. 

So far, the team have found at least 30 positive leads. 

Evidence is set to be shared with the Environment Agency, which usually leads the investigation of major fly-tipping and large scale waste crime.

Bill Chapple OBE, Cabinet Member for Planning and Environment, said: "It’s clear from our initial investigation that dumping on such a huge scale as this is the result of waste crime activities, rather than one off ‘fly-tipping’ as we would usually view it.

"Nevertheless, we have a zero-tolerance attitude to any form of waste dumping in Buckinghamshire and we’ll do everything we can to help ensure the culprits are brought to justice.”

Cllr Chapple added that the County Council is working closely with the Environment Agency, Highways England, several police forces and councils as the arms of the investigation to trace the criminals extend across southern England.
