SINN Féin leader Gerry Adams has been arrested in Northern Ireland in connection with the murder of Jean McConville in 1972, according to the Police Service of Northern Ireland.
The then 37-year-old widow and mother of 10 was kidnapped from her flat in the Divis area of west Belfast, and shot dead by the Irish Republican Party (IRA).
The IRA admitted to killing Mrs McConville in 1998, but her body was not found until 2003, when it was recovered from a beach in County Louth.
Police said a 65-year-old man had presented himself to Antrim police station on Wednesday evening and was arrested, according to BBC News.
Mr Adams confirmed his own arrest on Wednesday in a prepared statement, and described it as a voluntary, prearranged interview.
He said that he was "innocent of any part" in death of McConville.
