Bar 47 - an invitation-only basement operation where members were given swipe cards to gain access to private parties on Friday and Saturday nights - was raided yesterday by officers who seized more than $20,000 worth of alcohol, a dancing stage and other items before shutting it down. Police believe the venue was also used to distribute illicit drugs, with officers apparently ripping open the ceiling during their search. No one was at the premises during the raid. Senior police said they were investigating links between the bar and members of an outlaw motorcycle gang, believed to be the Hells Angels. The property at 47 York St is owned by former Sydney property developer and multi-millionaire Albert Bertini, who recently moved to France. There is no suggestion Mr Bertini was involved with the bar or with the Hells Angels. Police had heard of wild parties in the basement, with the raid the culmination of a lengthy investigation.
