Gerry Adams remains in custody over McConville murder
Sinn Féin leader Gerry Adams continues to be questioned by Northern Ireland police in connection with the 1972 murder of Jean McConville.
Mr Adams has spent the night in custody after going to Antrim police station, where he was arrested.
Speaking before his detention on Wednesday evening, Mr Adams said he was "innocent of any part" in the murder.
Mrs McConville, a 37-year-old widow and mother-of-10, was abducted and shot by the IRA.
Her body was recovered from a beach in County Louth in 2003.
Police said a 65-year-old man presented himself to officers at Antrim police station and was arrested.
In a statement, Sinn Féin said: "Last month Gerry Adams said he was available to meet the PSNI about the Jean McConville case. That meeting is taking place this evening."
Mr Adams added: "I believe that the killing of Jean McConville and the secret burial of her body was wrong and a grievous injustice to her and her family.
"Well publicised, malicious allegations have been made against me. I reject these. While I have never disassociated myself from the IRA and I never will, I am innocent of any part in the abduction, killing or burial of Mrs McConville."
His party colleague Alex Maskey condemned the timing of the arrest, just over three weeks from the European and local government elections.
However, Mrs McConville's son Michael, who was 11 when his mother was murdered, welcomed the arrest. "We're just happy to see everything moving as it is moving at the minute," Mr McConville said.
"Me and the rest of my brothers and sisters are just glad to see the PSNI doing their job. We didn't think it would ever take place [Mr Adams' arrest], but we are quite glad that it is taking place. ...
... Mrs McConville, one of Northern Ireland's Disappeared, was kidnapped in front of her children after being wrongly accused of being an informer. ...
