Gardaí investigating the murder of Denis Donaldson in county Donegal have arrested two men in connection with the investigation.

Donaldson was killed over 10 years ago in April 2006 at Cloghercor in Doochary.

He was a former Sinn Féin politician and official, and was murdered less than a year after being exposed as a British spy.

Two men, aged in their 40s and 70s, were arrested in the Donegal area today and both men are currently being detained at Letterkenny Garda Station.

Gardaí are now appealing for anyone with information in relation to this murder to contact them at the Incident Room at Letterkenny Garda Station at 074 9167100.
