The defenders crackdown on dealers selling dangerous bodybuilding drugs online. Plus they are on the trail of travel agents conning families out of thousands of pounds. And they take action against a golf club preparing food in filthy conditions.

The defenders take down a waste removal boss who illegally dumped 2,000 tons of rubbish in the Devon countryside - then set fire to it. They also crack down on an illegal puppy-farming gang conning people into buying sick and dying dogs.
