The 52-year-old actor is currently promoting his new movie 'Gravity' at the Venice Film Festival and after he was photographed steering a boat on Thursday, a local lawyer reported him to officials.
According to La Nuova Venezia newspaper, attorney Mario D'Elia complained and asked police to check if George has a nautical licence and a permit to drive a water taxi.
George likes to enjoy himself at the annual film gala with Bill Murray recently revealing he and the star pushed someone in a wheelchair into a swimming pool the first time they met each other at the festival a few years ago.
Bill explained: "I met him (Clooney) at the Venice Film Festival a few years ago and it's one of those places where people from Hollywood who are square like 364 days of the year, they will get weird in Venice. I don't know why, I don't know if it's the smell of the water or what, but all of these Hollywood kinds get crazy but not George, he's not one of them.
"We ended up having a whole lot of fun and my son said to me, 'Why were you and George Clooney pushing someone around in a wheelchair into a swimming pool?' I was like, 'You know son, why do you believe stuff like that? You know people put that in the internet, why would you ever believe something like that?' His response was, 'Well there are pictures.' "
