Mario Sergio Freudenthal from Itapetinga, Brazil would reportedly only do business with addicts if they got his surname 'Freudenthal' tattooed on themselves.
More than 70 people had his name inked.
Police found the tattoo on robbery suspects and deceased people. Because Freudenthal was the only man with that surname in Itapetinga, he was easily found.
Recently, a woman in New Zealand put tattoo space on her bum up for auction.
