The man - one of 96 outlaw bikies with an order baring( surely its barring!) them from pubs, clubs and restaurants - was spotted by police at an entertainment venue in Hindley St in the city at 1.55am on Sunday.
He was arrested for breaching his order and has been
bailed to appear before the Adelaide Magistrates Court on 15 March 2013.
Police have served 96 barring orders to Finks and Hells Angels members
and associates since establishing Operation Alpha after the November 21
shooting murder of Jason De Ieso in his Pooraka custom paint and panel
workshop.
They say barring orders "protect the public and reduce the potential for violence at licensed premises".
But some hospitality venue owners say it is too dangerous and difficult for them to enforce the orders.
The almost 100 orders were served as part of police Operation Alpha, set up to deal with the escalating violence between the Finks and Hells Angels outlaw motor cycle gangs.
The arrest comes a fortnight after the Sunday Mail published the images of 64 bikies with barring orders amid reports hospitality staff were fearful of enforcing the orders.
