The Congress Monday renewed its demand for a Central Bureau of Investigation (CBI) probe into an alleged multi-million-rupee scam in which paddy was procured from the farmers by cooperative societies in Bharatiya Janata Party (BJP)-ruled Chhattisgarh.

"The BJP government is trying to cover up the scam. A CBI probe is the best option to unravel the truth how the co-operative societies procured thousands of tonnes of paddy only on paper," state unit Congress general secretary Ramesh Varlyani told IANS.
