Fourteen people remain in Garda custody tonight in connection with the murder last year of 28-year-old Limerick rugby player Shane Geoghegan.
Seven men and seven women were arrested yesterday during a series of early morning raids on properties in counties Limerick, Tipperary and Dublin in a preplanned operation involving more than 70 gardaí.
The majority of the arrests were made in Limerick where a total of 12 people were arrested by gardaí yesterday morning at several addresses on the southside of the city.
Five men and five women were arrested at 7am, while two more people, a man and a woman, were arrested at 11am as part of the Garda operation.
A 41-year-old man was arrested near Bansha in Co Tipperary while a woman in her 20s was arrested in Coolock, Dublin.
A small quantity of drugs, believed to be heroin, as well as drugs paraphernalia, were found during the search in Co Tipperary.
The 14 people arrested range in age from late teens to early 40s.
Some are detained under section 30 of the Offences Against the State Act, while the others are being held under section 50 of the same Act.
They are in custody at separate Garda stations in Limerick and also at stations in counties Clare, Dublin and Tipperary. It is understood the majority of those arrested are being questioned in relation to withholding information about the murder of Mr Geoghegan, who was shot dead in a case of mistaken identity last November.
