Modi is likely to launch Bharatiya Janata Party's campaign for the upcoming assembly polls in the state from Muzaffarpur, around 70 km from Patna.
"The Bihar government will not take any chance and will go for unprecedented security cover during Modi's rally in Muzaffarpur," a state home department official said.
Although Modi's security is looked after by the Special Protection Group (SPG) - an elite commando force - the Bihar government has directed some of its senior officers to prepare special security arrangement for his rally, the official said.
"Bihar will be on full alert during Modi's rally," said a police officer of additional director general rank.
The Bihar government has asked the concerned officials to ensure full proof security as Modi's rally on October 27, 2013 in Gandhi Maidan here was rocked by serial bomb blasts. Modi was then the BJP's prime ministerial candidate.
At least five people were killed and nearly 100 injured in the October 27, 2013 blasts.
After Modi kicks off BJP's campaign rally, the party would hold one lakh meetings in 100 days ahead of the upcoming Bihar assembly polls, Ananth Kumar, who is the party in-charge of Bihar polls, said.
BJP has decided to use 160 high tech 'raths' (chariots) to reach out to people in villages.
"One high tech rath of the party will visit at least five villages in a day to hold public meeting, in one day, the BJP will reach to 800 villages spread in 243 assembly seats across the state to counter the propaganda by the new combine of JD-U, RJD, Congress and NCP," Ananth Kumar said.
Ananth Kumar said that BJP is the only party which has already reached to all 62,000 polling booths in the state.
"The BJP has 21 workers at each polling booth.They are fully ready to take on the alliance of chief minister Nitish Kumar and RJD chief Lalu Prasad," he said.
He said that BJP has finalised its preparation to go to rural parts of Bihar, particularly villages, to end the possibility of the return of 'jungle raj'.
