Concerned over the blast at the Patna Railway Station and recovery of two more crude bombs, the Ministry told the state government to send a report about the nature of the bomb, suspected persons or organisations which could be behind it and steps taken to maintain law and order, official sources said.
The Centre also decided to send a team of explosive experts of the NIA to help the Bihar police in post-blast investigation, they said.
A bomb exploded in a toilet at Patna railway station today injuring a person while two more bombs were recovered from the area, barely kilometers away from Gandhi Maidan where BJP's prime ministerial candidate Narendra Modi will be addressing a rally.
