Gardaí investigating the murder of Shane Geoghegan in Limerick are continuing to question 14 people.
The seven men and seven women were arrested during a series of raids in Limerick, Dublin and Tipperary yesterday.
They are being held at a number of garda stations across four counties.
28-year-old Shane Geoghegan was shot dead near his home in Dooradoyle in November in what gardaí believe was a case of mistaken identity.
