A man will appear before a magistrate in Belfast tomorrow charged with the attempted murder of top loyalist Mark Haddock.
He was arrested by police who carried out new searches in the city yesterday in a bid to hunt down the gunmen who shot Haddock on Tuesday.
Haddock, 37, was shot six times after going to a meeting in Newtownabby, County Antrim.
He was on bail for the attempted murder of a nightclub doorman.
A judge is expected to deliver his verdict in that case soon.
Since his release, Haddock has been ordered to stay out of Belfast because of fears his presence could ignite loyalist violence.
Those concerns were fuelled by claims that he had been a police informer while based in the Mount Vernon estate, a notorious Ulster Volunteer Force stronghold in the north of the city.
Police want to speak to anyone who say a blue Renault Clio on the Doagh Road, where the shooting took place, on either Monday or Tuesday.
The car was later discovered destroyed by fire a mile away in the Monkstown estate.
A second man arrested on Friday in connection with the shooting has been released without charge, police said today.
