Eight of the nine men arrested in Limerick yesterday in connection with membership of a dissident Republican group are to appear at the Special Criminal Court tomorrow.
The detainees are from counties Clare, Tipperary, Kildare and Limerick and were arrested during a meeting at a house in the city.
Security sources said the men were arrested on suspicion of membership of the "Continuity IRA".
The other man and a woman arrested in Limerick City as part of the same investigation were released this afternoon.
