An Argentinean football fan is suing a tattooist who drew a penis on his back instead of his favourite team's badge.

The teenager, who cannot be named, asked to have the Boca Juniors logo on his back.

But the tattoo artist was a supporter of rival team River Plate and decided to have some fun at his young customer's expense.

The victim told Terra Argentina: "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."

A police spokesperson said: "The tattooist supports Boca Junior's rival, River Plate, so he got annoyed when the teenager asked him to tattoo Boca's symbol and decided to tattoo a penis instead. Unbelievable!"
