Belfast bomb: Woman, 35, arrested over attack on prison officer
Police investigating a bomb attack on a prison officer in Belfast have arrested a 35-year-old woman in the Belfast area.
The 52-year-old, a married father of three, required surgery after an explosive device detonated under the van he was driving on Friday March 4.
The woman was taken to Musgrave Serious Crime Suite for questioning.
Detectives have also been granted an additional 24 hours by a court to question three men aged 34, 39 and 45 who were arrested on the evening of Sunday in relation to the investigation.
A group calling itself the New IRA claimed to have carried out the attack.
In a statement to the BBC the dissident republican group reportedly said the officer was targeted because he was involved in training other guards at Maghaberry high security jail, near Lisburn.
They said the officer was one of a number on a list of potential targets and the attack arose from a dispute over the treatment of dissident Republican inmates.
The group also claimed to have used the plastic explosive Semtex and a commercial detonator in the attack.
Following the blast, police commanders expressed fears that it could be the first of a number of dissident republican attacks to mark the centenary of the Easter Rising.
