SINN Fein leader Gerry Adams has been arrested by police in Northern Ireland over the 1972 murder of Jean McConville.

Mr Adams, 65, was in police custody last night after he voluntarily attended a station in Antrim for a pre-arranged meeting with the Police Service of Northern Ireland (PSNI).

In a statement, the PSNI said: "A 65-year-old man has been arrested this evening in connection with the abduction and murder of Jean McConville in December 1972."

Mrs McConville, a 37-year-old widow and mother of 10, was abducted from her flat in west Belfast in December 1972 and shot dead by the IRA. The claim she was an informer was dismissed after an official investigation by the Northern Ireland Police Ombudsman.

Her remains were recovered from a beach in County Louth in 2003, some 50 miles from the family home.

The arrest of Mr Adams comes after a US court ruled that Boston College must hand over recordings of interviews with republicans about Mrs McConville's murder to the PSNI.

Mr Adams said: "While I have concerns about the timing, I am ­voluntarily meeting with the PSNI this evening. As a republican leader I have never shirked my responsibility to build the peace. This includes dealing with the difficult issue of victims and their families. Insofar as it is possible, I have worked to bring closure to victims and their families who have contacted me. Even though they may not agree, this includes the family of Jean McConville.

"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."

However, Mr Adams said he rejected "malicious allegations" made against him, adding: "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."

Last month, Ivor Bell, 77, a leader in the Provisional IRA in the 1970s, was charged in connection with the murder. Mr Bell contests the charges.
