The Rebels outlaw motorcycle gang clubhouse was the target of a firebomb attack in Brisbane's CBD Saturday night.
About 11.10pm, police were called to the clubhouse on Frodsham Street, Albion, after reports of a fire.
Initial investigations suggest an accelerant was thrown at the building, with no-one injured and no major structural damage.
The clubhouse has been targeted in the past. In 2007 it was destroyed by fire and in 2012, after being rebuilt, was peppered with gunshots.
Investigations are continuing.
