A man extradited from Scotland and charged with the murder of a former Sinn Fein official in 2006 | World News

A man has appeared in a Dublin court after being charged with the murder of a former Sinn Fein official who was shot dead 20 years ago.

Denis Donaldson, 55, was killed in a remote cottage in County Donegal in April 2006, months after admitting his role as a police officer and MI5 agent for two decades.

Antoine Duffy, aged in his 40s and of no fixed address, has been charged with the murder of Mr Donaldson in Cloghercor, Doochary.

He was also charged with the attempted murder of a second person in County Donegal in November 2007.

Duffy appeared before the Special Criminal Court on Dublin on Monday afternoon.

He was previously arrested by Irish police after arriving at Casement Aerodrome in Baldonnel, on the western outskirts of the city, following his extradition from Scotland on a European Arrest Warrant.
