Das further added that the State Government, in order to restore proprietary of land back to the tribal people, has also formed a Special Investigating Team (SIT) which will start functioning by August 15.“I personally appeal to all the ex-proprietor brothers and sisters to register their complaints with the SIT who have ever been duped or cheated of their land by anyone,” said the CM. Complaints could also be registered online from August 15, added the CM.
