Shankill bomber arrested in connection with murder of Kevin McGuigan
IRA Shankill bomber Sean Kelly is being questioned by police after a man was shot dead in Northern Ireland.
Kelly killed nine people when he blew up a fishmongers in 1993. He was released from prison under the Good Friday Agreement.
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 Northern Ireland peace process.
Stormont's First Minister Peter Robinson has warned Sinn Fein 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 Fein has rejected the suggestion of IRA involvement.
