Deputy Collector Dharmenda Kumar lodged an FIR at Town police station against Singh, his private secretary Jitendra Singh and unidentified supporters for obstructing government work by breaking a barricade during filing of nomination by the MP from the Maharajganj parliamentary seat on April 15 last, the sources said.
As per the complaint, Singh and his supporters had broken the barricade set up near Town police station chowk and stormed into the district collectorate premises for filing of nomination by the RJD MP against permissible entry of only five persons, they said.
Meanwhile, district officials were probing allegations against Singh that he had instigated party workers to cast more than one vote.
Addressing an election meeting at the Zilla School Maidan along with former Chief Minister Rabri Devi after filing of nomination by her from the Saran parliamentary seat on April 12, the RJD MP had allegedly exhorted party workers to press buttons on EVMs more than once and use all means to bring loyal voters to polling stations on election day.
A CD has been made available to the MP and a reply is awaited, official sources said.
