Congress's Sachin Pilot, detained by the police amid the mega protest over Rahul Gandhi's questioning by the Enforcement Directorate for the third consecutive day, told NDTV today that the kind of force the police have been using on the Congress workers for the last three days "has never been witnessed before". "This is a very bad sign for a healthy democracy. It is unprecedented. How can the police enter the headquarters?" Mr Pilot told NDTV from the police station.
