The Jabalpur police have filed their first chargesheet in the sex-for-marks scandal in NSCB Medical College,focusing on a racket that helps students clear examination by paying money. A top police officer said though the possibility of girls having been asked to sleep with certain persons cant be ruled out,the evidence collected so far pointed to an organised syndicate involving officials of the Jabalpur College and Rani Durgavati University,to which it is affiliated. A first-year student had alleged in February that Prerna Otwal,her senior and hostel-mate,had told her in advance that she was going to fail in two subjects,but could clear them if she was ready to sleep with one Raju Khan,a contractor and former student leader. Khan and Otwal,a third-year student,are among the seven persons named in the chargesheet. Former Registrar Vijay Sharma,Examination Controller S S Rana,Deputy Registrar Ravindra Kakodia,and two employees of the universitys confidential section,Jaideep Pande and Pradeep Shukla,are the remaining accused named in the 400-odd page chargesheet.
