Shankill bomber Sean Kelly questioned by police investigating Kevin McGuigan shooting
IRA Shankill bomber Sean Kelly is being questioned by police after a man was shot dead in the North.
Kelly killed nine people when he blew up a fishmongers in 1993. He was released from prison under the Good Friday Agreement.
A 32-year-old woman has been arrested by detectives investigating the murder of Kevin McGuigan. She was detained by detectives from the Serious Crime Branch and taken to Antrim police station.
Kevin McGuigan Snr, a 53-year-old father-of-nine, was gunned down in East Belfast in a suspected feud between former IRA members.
He was hit a number of times at point-blank range in front of his wife Dolores outside their home in Comber Court last Wednesday.
Mr McGuigan was suspected by some in the republican movement of involvement in the murder of former IRA leader Gerard "Jock" Davison in the nearby Markets area of Belfast three months ago.
There has been widespread speculation his killing was a revenge attack by Mr Davison's one-time republican associates, which could have major implications for the North's peace process.
Stormont's First Minister Peter Robinson has warned Sinn Féin it would face expulsion from the power-sharing Executive if the IRA was responsible.
Mr McGuigan's relatives have used social media to accuse the IRA.
However, Sinn Féin has rejected the suggestion of IRA involvement.
Kelly is among four men, aged 39, 53, 44 and 41 respectively, who are being questioned by detectives.
Weapons recovered during searches in Greater Belfast have been sent for forensic examination, the Police Service of Northern Ireland (PSNI) said.
The Shankill deaths were among the most notorious of the later years of the Troubles.
IRA bombers intended to target paramilitaries they believed were meeting upstairs in one of the most famously loyalist parts of the city. Instead they ended the lives of nine innocent shoppers and left dozens more injured.
One of the bombers, Thomas Begley, also died in the blast in the packed fishmongers after the device exploded prematurely. The attack took place on a busy Saturday afternoon in October 1993.
A total of 57 people were injured, some seriously. Among them was a 79-year-old woman and two two-year-old boys.
The old building collapsed in a pile of rubble, sending a cloud of dust billowing across the road. People tore at the masonry in search of survivors.
The republican attack happened just a year before the IRA's ceasefire, which paved the way for peace. But at the time it helped unleash a loyalist backlash in which many more innocent Catholics were killed.
In revenge for the attack, the loyalist Ulster Defence Association (UDA) carried out a series of retaliatory attacks, killing eight people at a Catholic bar in Greysteel near Derry shortly afterwards.
Police today arrested a 49-year-old man in Belfast.
Detective Chief Inspector John McVea said: "The suspect has been taken to the serious crime suite at Antrim police station for questioning. Four other men arrested yesterday remain in custody.
"A number of searches are currently taking place in various parts of Belfast."
