The Calcutta High Court on Thursday ordered the CBI to register a fresh case in connection with alleged irregularities in the appointment of assistant teachers for classes 9 and 10 in government-aided schools, and interrogate former advisor of West Bengal School Service Commission (SSC) S P Sinha while holding that he made a false statement before the court. The court gave the agency a free hand to interrogate any person they think fit, whatever be his social or political status. The CBI had registered an FIR on Tuesday, with regard to similar allegations in a different petition by Lakshmi Tunga, on an order of the high court against a former deputy director, Directorate of School Education, West Bengal. Justice Abhijit Gangopadhyay on Thursday observed that this matter, on a petition by Anindita Bera, is also required to be investigated by CBI by registering a new case as it relates to the appointment of assistant teachers in classes IX and X. "The CBI is directed to investigate the matter and to interrogate Dr Santi Prasad Sinha especially and other members of the committee again in this matter in view of the startling revelation made," Justice Gangopadhyay said.
