Nagar has successfully campaigned against many government policies such as an increase in stamp duty and the transfer of Noida city funds outside the city. During the Ayodhya protest, he was detained by police for 21 days in
Saharanpur Jail. He was also detained for challenging the then Noida Authority Chairperson
Neera Yadav and sent to custody in
Meerut. He was jailed several times and arrested a dozen times for his involvement in farmers' rights agitation and District reinstatement protests. He also started agitation against hike in electricity charges in Noida in January 2016. Nagar started protesting against the toll collection on the
DND Flyway in 2014 and held many strikes. In 2015, he organised a massive car rally to raise awareness against it. On 28 August 2016, he started an indefinite protest against the toll and was arrested on the following day after staging an overnight protest and making DND toll free for two days. On 26 October 2016, the
Supreme Court of India ordered that the flyaway should be toll free. On 27 December 2016, Nagar protested against the exploitation of 21,000 land allottees by Yamuna authority and filed a
Public Interest Litigation in
Allahabad High Court. The protest was successful as the allotment was started by the authority within few weeks. == Controversies ==
