New Delhi, May 24: The CBI has filed a charge sheet against five suspects in a case of alleged sexual assault of a woman in Tamil Nadu's Pollacchi, officials said Friday. CBI spokesperson Nitin Wakankar said the charge sheet has been filed against Sabarirajan alias Riswanth, K Thirunavukkarasau, M Sathish, T Vasanth Kumar and T Vasanth Kumar in a special court in Coimbatore, less than a month of taking over the FIR for investigation. All the five accused are in judicial custody in Coimbatore jail, he said.

The agency has alleged that they were acting as an "organised criminal gang" and were in regular touch with each other. Citing the need for specialised attention, dedicated investigation with technical expertise and the extremely serious nature of the crime, the Tamil Nadu government had given its consent to transferring the harassment and a related assault case from the state's CB-CID to the CBI. Pollachi Sexual Abuse Case: Tamil Nadu Government Reveals Identity of Victim.
