A man has appeared before a Dublin court charged with the murder of former Sinn Fein official Denis Donaldson.

Mr Donaldson was shot dead in Co Donegal in April 2006, months after admitting his role as a police and MI5 agent over 20 years.

Antoin Duffy, aged in his 40s, of no fixed abode, appeared before the non-jury Special Criminal Court on Monday afternoon charged with the murder of Mr Donaldson at Cloghercor, Doochary between April 3 and 4 in 2006.

He was also charged with the possession of a shotgun and ammunition.

He was arrested earlier in the day following his extradition from Scotland on foot of a European Arrest Warrant.

Detective Garda Adrian Ahern told the court that he arrested Duffy at Casement Aerodrome in Baldonnel on Monday afternoon.

He said he later met Duffy at the Criminal Courts of Justice in Dublin, handed him a copy of the charge sheet and showed him an original copy of the charge sheet.

He was also charged with the attempted murder of another man in November 2007 in Co Donegal, and with possession of a shotgun and ammunition on the date and location in question.

Appearing before judges James Faughnan, Patrick McGrath and Sarah Berkeley, he was remanded in custody before the next court appearance on April 13 where he is to appear in person.

He was also granted legal aid by the court.
