Unionist politicians are calling for Gerry Adams to be arrested over Jean McConville's murder following claims from a former republican prisoner that he alone was in a position within the Provisionals to order the mother-of-10's brutal killing.
Evelyn Gilroy, an ex-internee from west Belfast, expressed her anger that six "low-level republicans" had been arrested this month about the 1972 murder while police hadn't even questioned the Sinn Fein president.
"Police have lifted people who were 15 and 16 at the time of the killing, yet Gerry Adams remains untouched," she said.
"The police should stop chasing those who were never in a position in the republican movement to order Jean McConville's execution and instead arrest the only person who was in that position – Gerry Adams."
Ms Gilroy was a member of the republican movement along with Mr Adams in the 1970s. She was active in Divis where Jean McConville was abducted. Mr Adams has always strongly denied any involvement in the horrific abduction and murder of Mrs McConville.
TUV leader Jim Allister said: "With even a former colleague in the republican movement, Evelyn Gilroy, now calling for Gerry Adams to be arrested over Jean McConville's murder, the police's inaction is becoming unsustainable. Continuing to treat Adams as an untouchable, in the face of such exposure, brings policing into disrepute."
Ulster Unionist minister, Danny Kennedy, said: "The increasingly compelling evidence against Gerry Adams cannot be ignored. It is beyond the time that he should be arrested and questioned. The PSNI must act now and it is in the public interest that they do so."
DUP MP Gregory Campbell said: "The comments about Gerry Adams from a republican active at the time of Jean McConville's abduction and murder have credence.
"They are the latest in a series which can't be easily dismissed by Sinn Fein.
"The police should question Gerry Adams as a matter of urgency. If charges are appropriate they should follow irrespective of the fact he is a TD."
Last month, Mr Adams told his solicitor to contact police to see if he is wanted for questioning over the murder. He said he is willing to meet the PSNI.
