Some guy was blackmailing Mario Balotelli with some photographs he'd taken in a nightclub and now he's been arrested, because that's not allowed.
I have no idea what the pictures had in them that made them so valuable, but rumours seem to suggest it was him drinking champagne in whatever nightclub he was in. This is about the least exciting thing it could possibly have been. The minute I heard he was being blackmailed I assumed he'd be doing something like setting fire to a prostitute while Harrison Ford played the harp, or that somehow he was doing something that involved tits. Whenever I hear the words 'blackmail' I instantly think 'tits will be involved somehow' but that's also partly due to the fact that I have watched an astonishing amount of pornography.
