Hundreds of BJP workers took part in the march which commenced at the party's state headquarters in Patna and concluded at the historic Gandhi Maidan, a few kilometers away.
Addressing party workers, Bihar BJP president Nityanand Rai said most incidents of killings of BJP workers in Kerala were reported from the home district of Chief Minister Pinnarayi Vijayan which hints at the patronage enjoyed by the attackers.
"The BJP under the leadership of Prime Minister Narendra Modi and party national president Amit Shah is on its way to achieving national footprint and our workers will not take such intimidatory tactics lying down. Even after CPI(M) depletes its cache of ammunition, there will be no dearth of BJP workers ready to take it on without any fear," he said.
BJP workers are capable of responding to violence but they are disciplined and believe in democracy, he added.
Meanwhile, RJD leader and former Bihar Deputy Chief Minister Tejashwi Yadav in a statement questioned the permission granted to BJP for taking out the march when his party was denied it.
"I wish to ask Chief Minister Nitish Kumar whether law is different for those in power and those in the opposition.
He should explain why our workers were not allowed to take out a march to Raj Bhavan on October 12 in protest against Srijan scam and why BJP was allowed to take out the Jan Raksha March," he said in a statement.
