Violent protests erupted in Chhapra on Wednesday over death of 27 school students after consuming mid-day meal.
Earlier, LJP chief Ramvilas Paswan slammed Bihar Chief Minister Nitish Kumar over the deaths and demanded his resignation saying these are "not death but murder".
Paswan also castigated Kumar for bomb explosions in Hajipur alleging "no law and order exists in Bihar".
Seeking Kumar's resignation over the incident of the death of students in Chhapra, he said it "exposes" the claims of good goveranance of Nitish Kumar.
"This (death of students) is not simply death but murder of children for which Bihar government and the Chief Minister are responsible. He should resign immediately", Paswan said.
He demanded a probe by sitting High Court judge and a compensation of Rs 20 lakh to the family of the deceased.
Expressing concern over the incident of bomb blasts inside the civil court premises in Hajipur to free a dacoit, the LJP chief said, "law and order is non-existent in Bihar. Today, there were two blasts. Last week, there was a blast in Bodhgaya. There is no law and order in the state and corruption is at its peak."
While Chhapra falls in the Lok Sabha constituency of RJD President Lalu Prasad, Paswan had been representing Hajipur for decades before losing in 2009 Lok Sabha polls to JD(U).
