Sinn Fein president Gerry Adams has voluntary presented himself to police investigating the abduction and murder of Jean McConville in December 1972.
A statement on the Sinn Fein website said Mr Adams submitted himself to questioning by the Police Service of Northern Ireland as part of their investigations.
Mr Adams said: “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.
