Kolkata: The CBI told the Calcutta HC on Friday that the charge-sheet in the Narada sting tapes case will be submitted in a month if necessary procedures are completed. Additional Solicitor General Kaushik Chanda told the court of Justice Joymalyo Bagchi that the agency was close to "stitching up" the case and will submit chargesheet in about a month if sanctions from authorities are received since the matter involves MPs and MLAs. Chanda said this during the hearing of a petition by TMC MP Aparupa Poddar.
