The Supreme Court will tomorrow hear a plea from the Mamata Banerjee-led All India Trinamool Congress (TMC) alleging "sustained campaign" of violence against party members in Tripura and demanding a Special Investigation Team (SIT) led by a retired judge to look into "deliberate police inaction" at the behest of political opponents who are in power in the state. Led by Biplab Kumar Deb, the BJP is in power in Tripura.
