GRP sources said about 150 papers, claimed to be petitions of depositors from Murshidabad and Jharkhand, were spotted lying on the sides of the rail track at Purbo Satgachia station by local residents.
Locals claim that on close examination they found the papers were apparently submitted to the probe panel investigating into the Saradha fraud by depositors and agents and smelt a cover-up bid, but GRP sources say the papers would be passed on to West Bengal police for verification.
The Commission had so far received over four lakh complaints along with appeals for return of their deposits.
