Police have been secretly watching the set of George Clooney's film sequel Ocean's Twelve in Sicily, as part of an investigation into the local mafia.
Inquiries revealed that some mafia suspects were seen loitering near the set. They may have been looking to blackmail film-makers or concerned about the discovery of an alcove used for arms.
The Ocean's Eleven follow-up - starring George Clooney, Brad Pitt and Julia Roberts - is due out in 2005.
