An FIR has been lodged against Vishwas and 20 other unknown people in Sadar Kotwali police station, district magistrate Pradip Kumar Yadav said.
"Kumar Vishwas had come to the district in a cavalcade last night, disrupting traffic on busy roads, without prior permission from the administration," Yadav said.
Vishwas, on the other hand, claimed that he had gone alone in one vehicle and hence there was no violation of model code of conduct.
On March 5, Raj Kumar, a labourer belonging to Gauriganj area of Amethi, was buried after the building in which he was working collapsed and rescue operations are on to save him.
Vishwas also alleged that the administration was lax with contractors of the building and demanded an FIR against the DM and SP in this connection.
