Illegal waste found dumped in Staffordshire warehouse
The owners of a warehouse are facing a clean-up bill of nearly £1m after thousands of tonnes of illegal waste were dumped there.
More than 5,000 tonnes was left at the site in Staffordshire by a company the landowners thought was a legitimate firm.
BBC research has found the number of incidents of large-scale fly-tipping has more than doubled since 2012.
Marc Lidderth, from the Environment Agency, which is investigating the Staffordshire case, blamed organised criminal gangs and added cases were "becoming very complex".
