Two men are still being questioned about the illegal possession of a shotgun, which was seized in searches carried out by gardaí investigating the assault on security guards protecting a repossessed house outside Strokestown last Sunday.
According to the Irish Independent, the period of detention for the two suspects was extended for a further 24 hours by a Garda chief superintendent yesterday.
The men, aged in their 50s and 60s, were arrested by officers from the Garda Special Branch during searches at three houses on Wednesday morning.
Gardaí seized the gun, along with a lorry, a teleporter and mobile phones, during the raids.
Documentation and phones were also seized in searches in Navan, and Blanchardstown, Dublin, on Monday.
Although there were no further arrests yesterday, gardaí continued to interview potential witnesses.
