Late last month, the Madhya Pradesh Police seized two railway rakes that were found allegedly unloading coal rejects from a washery at a siding used by the railways at Singrauli near the Jharkhand border.
These were allegedly from Barkakana in Jharkhand and suspected to have been brought by a Kolkata-based trader for blending with other coal stocks and selling in the open market, people in the know of the matter said.
