A Garda spokesman confirmed to Donegal Daily that the man arrested was detained after a search of a house in Ballyshannon.
The suspect is in his 40s.
A rifle was recovered during the search which came just days after a weapon was taken during an incident in Glenties where a 77-year-old man was battered and robbed by a vicious gang of burglars. It’s not known if the cases are linked at this stage.
“A male aged in his 40s was arrested at the scene. He is currently detained under Section 30 of the Offences against the State Act, 1939, at Ballyshannon Garda Station,” said a spokesman.
The suspect can be held for up to 72 hours.
