Several Congress leaders were placed under house arrest in Telangana on Thursday ahead of state party chief Revanth Reddy's appearance before SIT to submit evidence in the TSPSC exam paper leak case. The detained leaders include ex-MP Mallu Ravi and state Mahila Congress President Sunitha Rao. "CM K Chandrashekar Rao [is trying] to suppress the protests of Opposition," Revanth said.
