All of those held during the past two days have been detained under the terms of legislation permitting suspects to be kept in custody for up to 48 hours. The latest arrest, of a man, was made yesterday morning. A man and a woman held after leaving a ferry from Anglesey, at Dun Laoghaire, Co Dublin, on Wednesday, and three other men picked up later, are also being questioned.
Ms Guerin was shot dead in her car in Dublin last June. More than 100 arrests have been made, but only one man has been charged with the murder.Reuse content
