Social activist and environmentalist Prafulla Samantara, who was picked up by police on Tuesday and later released after five hours, on Wednesday accused the Odisha government of unleashing terror in the mining areas to stifle the voice of the Opposition as well as the local tribals.

Winner of the Goldman Environmental Prize for 2017, Samantara, 72, told The Telegraph: “I was about to address a media conference at Rayagada on the plight of those tribals who were opposing the mining activities in Rayagada, Kalahandi and other adjoining areas, but three unidentified people forcibly entered into my hotel room and took me away with them. On the way, I came to know that they were plain-clothes police. Later, they left me at my house in Berhampur around 9.30pm after an almost five-hour journey.”

Berhampur is the southern commercial town of Odisha and about 225km away from Rayagada, which borders Andhra Pradesh.

Samantara, president of the Lok Shakti Abhiyan, sent an FIR to the Rayagada police on Wednesday, stating how three people in civil dress entered his hotel room at Rayagada on Tuesday, snatched away his two phones, tied his hands back and covered his head and face with a towel and forced him to come out of the hotel room and go with them in their four-wheeler. He also pointed out how he was subjected to mental torture.

Samantara said: “Around 24 tribals were put behind bars in Rayagada sub-jail for opposing the mining activities. All of them were in jail in three spates of arrests between August 13 and August 20. They were against the mining of bauxite at Sijumali and other areas in Rayagada district.”

He added: “On Tuesday morning, I reached Rayagada and went to jail to meet them. I was about to address the media to expose the nexus between the government and industrial houses. Before I could address the media at Rayagada, the police abducted me. Later realising that it would bring more trouble, they were forced to release me. It’s a kind of state-sponsored terrorism.”

Samantara said people opposed leasing bauxite mines to Vedanta and Adani groups. “In the name of industrialisation, the indiscriminate mining of bauxite would ruin the areas.”

“The Odisha police have unleashed severe repression by resorting to mid-night raids and abductions. Charges of Unlawful Activities (Prevention) Act have been foisted on activists opposing the mining of bauxite in their areas,” he said.

According to the environmentalist, the state and the Centre — the BJD and the BJP — are collaborating in accelerating the acquisition of bauxite reserves. Both the ruling establishments seek to stifle the voices of these movements by putting their leaders and active members behind bars.

Despite making a number of attempts, Rayagada superintendent of police (SP) could not be contacted.

Rayagada police station inspector said: “I am yet to receive the FIR copy. I have no idea about the alleged abduction by police.”
