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". No reason was cited for the police action, Mr Pilot said. "We wanted to enter our own office. But the police and the Centre have made their mind that no opposition will be allowed," he added.
