Gardaí in Cork have arrested a British man on suspicion of making threats to kill a Westminster MP.
The man (41), from England, was detained in Douglas on Saturday.
The arrest was made as gardaí executed a search warrant at a residential property.
A Garda spokesman said: “During the course of the search a number of electronic items were seized and one man, 41, was arrested on suspicion of making threats against a person from outside of this jurisdiction.”
The Irish Times has reported that the person who received the threats is a female Labour politician.
The man has been detained under Section 4 of the Criminal Justice Act. He is being held at Bridewell Garda Station in Cork.
The arrest follows the fatal stabbing of Conservative MP David Amess, as he held a constituency surgery in Leigh-on-Sea in Essex on October 15th.
Ali Harbi Ali (25) has been remanded in custody charged with murdering Mr Amess.
