An already busy street in Newcastle’s CBD was crawling with heavily-armed police this morning, as the State Crime Command’s Gang Squad broke down a door and raided a suspected outlaw motorcycle gang clubhouse.

Detectives believe the two-storey building in King Street was recently converted into the headquarters of the Newcastle chapter of the Rebels gang.

Police have spent the day dismantling the building, removing furniture, alcohol and other items.

One person was arrested and is being interviewed by police.
