The Ministry of Home Affairs (MHA) on Thursday sought a detailed report from the West Bengal government over the attack on BJP National President J.P. Nadda's convoy.

The Ministry, in a written message to the state Chief Secretary, has asked to submit the report about the issue and lapses in law and order in the state that may lead to the risk for senior BJP leaders camping in the state ahead of the assembly elections that is just six months away, said sources privy to the development.
