Spread over in areas spanning from Jharkhand to Andhra Pradesh with command centres in jungles of four states of Chhatisgarh, Maharashtra, Odhisa and Andhra Pradesh, the funding issue of Naxals has been a cause of concern to the states as well as the central government.
In a written reply in Rajya Sabha, Minister of State for Home R P N Singh said it was nearly impossible to know the exact amount collected by CPI-Maoists but he quoted a study by Institute of Defence Studies and Analyses which had pegged the money at Rs 140 crore per year.
The main sources of funds for Maoists include extortion from contractors of 'tendu patta' (used to manufacture bidis), from infrastructure and development work contractors, 'levy' from businessmen and corporate houses, besides robbing banks and public and private properties to augment their finances.
"Further, the possibility of certain front organisations of the CPI-Maoists party clandestinely getting foreign funds cannot be ruled out," he said, adding Naxals "extort considerable 'levy' from various illegal mining mafia groups.
R P N Singh said the situation was being monitored closely and even the state governments had been advised to crack down against those who were extorting money.
