Gardai in Donegal have arrested a 70-year-old man tonight in connection with the murder of Denis Donaldson. We understand the man is being held detained at Letterkenny Garda Station on suspicion of withholding information. He can be held for three days.
The former head of Sinn Fein's Stormont offices was shot dead at his home outside Glenties in April 2006. He had moved to the remote cottage after admitting he had been a British agent for more than 20 years.
