Four men have been charged over the abduction of Quinn executive Kevin Lunney and will appear in court this morning.
Detectives probing the businessman's kidnap and torture lifted two 38-year-old men in Dublin early last Thursday morning.
And later in the afternoon, gardai struck again, arresting a 25-year-old man in the capital and another man, 66, in Co Cavan.
The two men arrested in the morning were detained at Ballymun and Finglas garda stations.
Meanwhile, the 25-year-old was quizzed at Irishtown in south Dublin and the pensioner was held at Monaghan garda station.
Now it has been confirmed that all four men have been charged and will appear in court in Co Cavan this morning.
A garda spokeswoman said: "The four males arrested on the November 21 were released overnight from detention under Section 50 Criminal Justice Act 2007.
"All four males remained in Garda custody and will appear before Virginia District Court, this morning, November 26, 2019 at 10.30am charged with offences in respect of this ongoing investigation."
