Patna: Lok Sabha member Pappu Yadav was on Sunday booked in the Bihar capital city in a case of instigating protesting students to immolate themselves, police said. "An FIR was lodged at the Buddha Colony police station by the district administration against Pappu Yadav for instigating students, demanding postponement of Bihar Public Service Commission (BPSC) main examinations, to immolate themselves," a district police official said. The Lok Sabha member from Madhepura constituency was last year expelled from the Rashtriya Janata Dal for six years for anti-party activities. According to reports, Pappu Yadav met the agitating students and extended support to their demand. He then allegedly instigated them to issue a threat to commit self-immolation to exert pressure on the state government. After meeting Yadav, the protesting students threatened to commit self-immolation if the Nitish Kumar government failed to fulfill their demand for postponing the BPSC exams so that it did not clash with the Union Public Service Commission's preliminary examinations.
