JMM leader Hemant Soren has lodged a complaint against police officer Anurag Gupta under the Scheduled Caste and Scheduled Tribe (Prevention of Atrocities) Act, 1989, for using "humiliating words" against him. Soren visited a police station here on Sunday night and produced a CD to claim that Additional Director General of Police (ADGP) Gupta met Congress leader Yogendra Sao and told him "they (Soren government) sent you to jail; they are tribal people and will not support you." Soren, who is Executive President of Jharkhand Mukti Morcha (JMM), said Gupta's words amounted to an affront to the tribal community. Sao was agriculture minister in the Jharkhand government that Soren headed from July 2013 to December 2014. He was arrested in October 2014 for floating an extortion group called Jharkhand Tigers. Sao was also an accused in the Beltu massacre in 2001 in which Maoists had killed 13 villagers in Jharkhand. The CD that Soren adduced in his complaint is the same that the Opposition has been using to claim that Raghubar Das government "rigged" the June 11 Rajya Sabha elections. It was made public on July 15 by Jharkhand Vikas Morcha (Prajatantrik) leader Babulal Marandi. It purportedly show ADGP Gupta meeting Sao and suggesting to him the political favours he and his wife - Congress MLA Nirmala Devi - will enjoy if they helped the BJP candidate win in the Rajya Sabha elections. The CD also had a purported conversation between Raghubar Das's political Advisor Ajay Kumar and Sao. The two seats in June 11 Rajya Sabha polls were won by the ruling Bharatiya Janata Party (BJP). The JMM candidate Basant Soren - who is Hemant Soren's brother - had lost despite the parties supporting him having the required number of votes to get him through.
