Police have arrested 12 people at the Occupy Brisbane protest, charging one 19-year-old man with assaulting police but releasing 11 without charge.

Officers have now forcibly removed 20 Occupy Brisbane protesters, which saw them fence off Queens Park in the CBD. The crackdown this morning caused traffic delays on Elizabeth Street and back onto the Riverside Expressway.

About 20 protesters marched to King George Square where they have regrouped and plan to meet at 5pm today to discuss their next move.

The second eviction in as many days came after in-fighting broke out amongst Occupy Brisbane protesters during an impromptu meeting, which saw the group split in two.

Some of the protesters wanted to move to King George Square, while others believed it displayed weakness and wanted to stay in Queens Park near the Treasury Casino.
