A MEMBER of the group known as the Hooded Men has written to PSNI chief constable Simon Byrne asking for an independent investigation.
Brian Turley took the step days after a court refused the PSNI leave to challenge a ruling linked to the case.
Police had sought permission to mount challenges to the Supreme Court after decisions were reached in three high profile cases, including that of the Hooded Men.
Earlier this year the Court of Appeal said that interrogation techniques used against the men would be torture if deployed today.
The court added that the men had a legitimate expectation that police would further investigate claims that their treatment was sanctioned by the British government.
In his ruling last month, Sir Declan Morgan said he would leave it to the Supreme Court in London to decide whether to take the case on.
The 14 Catholic men from across the north say they were subjected to state-sanctioned torture when they were interned in 1971.
None of the men were ever convicted of any wrongdoing.
The five techniques used included being hooded, made to stand in stress positions, forced to listen to loud static noise and being deprived of sleep, food and water.
Mr Turley last night said: “An investigation must be conducted, and it must be conducted by an independent police force."
