Human rights organisation 'People's Watch' sent a memorandum to P Amudha, the high-level inquiry officer who is conducting inquiry into the Ambasamudram custodial torture case, on Wednesday.

In the letter, Henri Tiphagne, executive director of 'People's Watch', urged Amudha to recommend use of provisions of Scheduled Caste and Scheduled Tribes (Prevention of Atrocities) Act against the police personnel stating that some of the survivors of custodial torture are from the SC community.

"The police personnel already knew that the suspects, tortured by them, are members of the SC community. The relevant provisions of the Act for 'witness protection', compensation and rehabilitation should be invoked without further delay," he added.
