A man in his 40s was arrested by Gardai on suspicion of dissident republican activity after Irish citizens serving in the British Army were threatened.

The Limerick man was detained at Henry Garda station in Limerick this morning under the provisions of Section 30 of the Offences Against the State Act 1939, following a search of a house in the city.

The Garda operation came after a warning made by the continuity IRA during a commemoration for Sean South.

It described Irish people in the British Army as “legitimate targets,” according to The Irish Sun.

A party figure for Republican Sinn Fein later denied any official involvement in the January 6 ceremony, where men in paramilitary uniforms carried Republican Sinn Fein banners ahead of the event.

The threat prompted Justice Minister Alan Shatter to issue a statement that dissidents would face the full rigours of the law.
