Police were called to Brad Pitt's hotel in Sydney, Australia on Monday (10Jun13) after an over-zealous fan attempted to get too close to the actor and his son.

The Hollywood superstar was leaving the city's InterContinental Hotel with his adopted son Pax, nine, on their way to a cruise around Sydney Harbour when they were approached by a man in the building's underground car park.

The fan - identified as Michael Joseph - was tackled by Pitt's bodyguards and police were called to the scene.

Officers issued Joseph with a warning and ordered him to move on.

A police spokeswoman tells the Sydney Daily Telegraph, "It was ascertained that, although being an enclosed public space, the car park was controlled land under the control of the hotel. The man was issued with a move-on order following the incident."

Pitt, who visited Australia to promote his new movie World War Z, went on to enjoy a day out on a yacht with his son, and they flew out of the country on Monday night.
