Jean McConville
A 56-year-old man has been arrested in connection with the murder of Jean McConville.
The man was arrested last month, but interviews had to be suspended on medical grounds.
He presented himself to police at Antrim police station on Wednesday morning.
It follows the release of Sinn Fein leader Gerry Adams on Sunday evening pending a report to the PPS.
Adams was questioned for almost 100 hours by police investigating the murder.
He has always denied any involvement.
