Officers bust a tenant making over £100,000 unlawfully sub-letting his council flat in London. They take down a criminal gang running a multi-million-pound diesel fraud. The gang has been contaminating diesel with cheaper products, which is saving them millions of pounds in tax and costing unsuspecting motorists thousands of pounds in engine repairs. And they help rescue over 150 dogs being kept in squalid conditions at an animal centre in Lincolnshire.
