Sylvester Stallone was detained for hours on arrival at Sydney Airport after officials found prohibited imports in his luggage and that of his entourage, media reported Saturday.

Australian Customs Service national investigations manager Richard Janeczko did not say what the items were or whose luggage among Stallone's party they were found in during a routine screening late Friday.

"As a result of having their luggage x-rayed, a number of prohibited items were seized by Customs," Janeczko told Ten Network television news. "Mr. Stallone was allowed to continue with his party and our investigations are continuing." He gave no other details.

Stallone emerged from the airport hours after his fellow passengers and signed autographs for fans, Ten reported. He declined to comment on the incident.

Stallone is in Australia to promote his movies "Rocky Balboa."
