Caan, 52, has described Mr Lorenzo as his 'best friend', and twice offered to pledge his home in Bel-Air, Los Angeles, as collateral for bail. Prosecutors in Los Angeles claim that Mr Lorenzo, 46, who has been in custody since June on dollars 2m (pounds 1.1m) bail, is a leading figure in the powerful New York-based Bonanno crime family. He faces life imprisonment without parole, if convicted.
Caan, who recently starred in the commercially successful film Honeymoon in Vegas, said that he knew of no crime committed by Mr Lorenzo. 'Had he, he wouldn't be my best friend.'
