A policeman is recovering in hospital in the North after he was shot in the back during internal loyalist feuding in Carrickfergus, Co. Antrim.
A bullet lodged in the officer's chest, but his injuries are not believed to be life threatening.
A man was stabbed during the violent clashes, after which, three men were arrested in a car when police found CS spray, a cross bow and baseball bats.
A power struggle has been waging within the UDA for months now.
Some leaders, like South-west Belfast commander Jackie McDonald, want to move on and leave violence and criminality behind. However those concentrated in north Belfast and south-east Antrim are resisting the move.
Several leaders of the dissident factions have been exiled by the UDAs inner council, but have later returned to defy the leadership.
With tensions mounting between the sides, it was only a matter of time before violence broke out.
It is feared that last night's violent scenes are not the end of this feud and police fear more bloodshed.
