Australia's most wanted man Malcolm Naden has been taken under heavy guard to Manning Hospital.
Officers from the Tactical Operations Unit and Dog Unit were sent to a house 30 kilometres west of Gloucester late last night after intelligence was received.
He was arrested after midnight following seven years on the run.
Officers surrounded the house and Naden came out briefly, before trying to escape through a back door.
"The police then again confronted him on that side, because we had the building contained, and a short scuffle ensued when he was then arrested," Assistant Police Commissioner Carlene York said.
Naden, who was bitten by a police dog during the arrest, was given a health check before he was taken to be interviewed.
He was taken from Taree Police Station to hospital about mid-morning.
