A woman was arrested today in connection with a blaze which claimed the lives of two firefighters last year.
Mark O’Shaughnessy, 26, and Brian Murray, 46, were killed when the roof of a disused factory on Lower Dargle Road in Bray, Co Wicklow, collapsed on them.
Detectives investigating their deaths, on September 26 last year, arrested the woman, aged in her 20s, on suspicion of reckless endangerment.
It is understood she is a member of the fire service.
The woman is being held at Bray Garda station under Section 4 of the Criminal Justice Act.
It is the second arrest in just over a month as part of a Garda and Health and Safety Authority (HSA) probe into how the part-time firefighters died.
A man in his 40s arrested last month was later released without charge while a file was being prepared for the Director of Public Prosecutions.
The families of the dead men appeared before an Oireachtas committee earlier this year and called for an independent investigation into the blaze.
Members of the New York fire service and representatives of then Taoiseach Bertie Ahern and President Mary McAleese were among thousands of people who attended the funerals of Mr Murray and Mr O’Shaughnessy.
Gardaí, the Health and Safety Authority and Wicklow County Council each launched investigations following the tragedy.
