Gerry Adams has made a formal complaint against the PSNI because he believes his rights were contravened during his detention last week.

The Sinn Féin President says he lodged the complaint about "one aspect of his interrogation" before he left the police station in Antrim on Sunday evening. He says he will discuss with his solicitor whether there is any call for further complaints.

Adams was questioned for four days in connection with the IRA murder of Jean McConville in 1972. He has continually denied having any involvement in McConville's kidnapping and murder.

Speaking in Dublin today, Gerry Adams said he believes his rights were contravened by the police – possibly twice – while he was held.

Mr. Adams was released without charge from Antrim Police Station on Sunday. A file will now be sent to Northern Ireland's Public Prosecution Service who will consider whether or not there is a case against the Sinn Féin politician.
