The FIR was lodged at Gauriganj police station here after authorities reviewed the video of Vishwas' campaign, Circle officer Naveen Kumar Singh said.
Kejriwal and Vishwas had allegedly violated the model code and prohibitory orders by holding roadside meetings without taking permission and disrupting traffic.
Earlier, an FIR was registered against Vishwas and 100 others on April 18 for staging a dharna inside Gauriganj Police Station to press for an FIR against Priyanka Gandhi, Rahul Gandhi, Vinod Mishra and others.
Kejriwal is in Amethi to campaign for Kumar Vishwas. Kejriwal held a roadshow and met locals as a part of the election campaign.
