A football fan in Argentina is suing a tattooist who drew a penis on his back instead of the Boca Juniors football team logo. The teenager had asked for his favourite team's design but, unbeknown to him, the tattoo artist was a supporter of rival team River Plate and decided to have a laugh. The victim, who cannot be named, said: "I could not see what he was tattooing because he didn't have a mirror. I only saw it when I got home and showed it to my parents."
