Filthy Rotten Scoundrels is the series that highlights the work of environment officers across the UK, as they tackle astonishing and flagrant cases of fly-tipping.

9000 tons of rubble has been illegally dumped in a swan sanctuary, with dire consequences for the wildlife. The Environment Agency is determined to bring the offenders to justice. Liverpool officers are hot on the heels of a serial fly-tipper brazenly dumping across their city and in Middlesbrough, there's a behind-the-scenes look at the CCTV system which talks back at people who drop litter.

The hard-working and tenacious officers often go undercover to track down the criminals who dump thousands of tons of rubbish on our streets and country lanes. Investigators call on police back-up for elaborate sting operations, and scan through hours of 24-hour surveillance footage. More than 3,000 fly-tipping incidents happen each day, costing tax payers 55 million pounds a year to clear up.
