A DISSIDENT republican is expected to be arrested over the coming days after a major arms dump was discovered in a ravine.
Gardai in Limerick are continuing their investigations following the seizure at Windy Gap, Meelick, on Saturday.
The discovery was made by a man out walking with his gundog in a wooded area.
A revolver, an imitation firearm, five smoke and SC gas grenades, several electronic detonators, timing devices for car bombs, balaclavas, woollen gloves, magazines for sub machine guns and pistols and 1,000 rounds of ammunition have all been seized.
An Army bomb disposal team was called to inspect the explosive devices after the discovery was made.
However, there was no need for any controlled explosions and all material was then handed over to gardai.
All weapons and items recovered are being forensically examined by officers.
It is believed some of the cache that was recovered had been there since the mid-1990s.
While investigations are at an early stage, officers believe it is connected to a RIRA faction based in Limerick city.
The discovery is said to be hugely significant but it has not been established if the weapons or explosive devices were to be used by dissident republicans in the near future or whether they were in long-term storage.
Gardai in Limerick expect to make an arrest over the coming days in connection with the find, it is understood.
