Willy Widdershins

Willy Widdershins was arrested by the Ministry of Magic for enchanting a series of Regurgitating toilets, one of which backfired against him during the creation. He was badly injured in his capture and was wrapped in bandages. He made a deal with the Ministry, that if he spied on Harry Potter and his friends, they would let him go. So he did so and he reported back to Dolores Umbridge and Cornelius Fudge that they were planning on making a secret Defence Against the Dark Arts group while they were in a meeting in Hog's Head. By doing so he was able to avoid prosecution. He was later caught selling Biting doorknobs, which bit off fingers of two Muggles, and was subsequently given a sentence that he could not avoid.
