The AICC general secretary also threatened to file an FIR against the "designated authorities" if he failed to get a "satisfactory" reply from the STF in this regard.
"If I don't get a satisfactory answer, I will file a complaint before the police authorities under section 154 of CrPC against the designated authorities, investigating agencies and others who are trying to screen the real offenders of the crime.
The letter was released to the media by Singh's office today.
SIT is monitoring the probe into the multi-crore scam which involved impersonation as well as favouritism in appointing candidates in jobs, referred by "influential" persons, apparently for pecuniary gains.
The Madhya Pradesh High Court had recently upheld the SIT's initial report that evidence--an excel sheet and a pen drive--submitted by a cyber expert-cum-whistleblower of the scam, was forged.
"I am appalled by the approach adopted by SIT in such a sensitive case.
"Instead of sending the pen drive and the report of the Truth Lab, Bangalore, regarding tampering of evidence by Indore police in crime no. 19-20/2013 for examination to a reputed central forensic lab, the SIT in a hurried manner, within five days of order passed by the high court dated April 16, chose to have a demonstration by Special Task Force (STF) and formed a prima facie opinion that contents in the pen drive are forged and to mislead the investigating agency," he said.
