Senior Congress leaders, including party president Sonia Gandhi, vice president Rahul Gandhi and former prime minister Manmohan Singh, on Friday courted arrest after they were stopped from going to Parliament House as part of their "Save Democracy March".The Congress leaders started their march from Jantar Mantar to Parliament House but were stopped by police as section 144, which prevents assembly of five or more persons in an area, had been imposed in the area. They later went to the Parliament Street police station to court arrest and were released after some time. A police official said the Congress leaders were at the police station for about 30 minutes. Former defence minister A.K. Antony, Leader of Opposition in Rajya Sabha Ghulam Nabi Azad, party's leader in Lok Sabha Mallikarjun Kharge, were among those who courted arrest. The march began after Congress leaders addressed party workers assembled at Jantar Mantar. The party had organised the march to protest against the NDA government, including its actions in Congress-ruled states of Uttarakhand and Arunachal Pradesh.
