This decision has been taken by the Home Ministry following a request from the Bihar government after the holiest Buddhist shrine was hit by serial blasts on July 7.
A top Home Ministry official said the Bihar government will bear the expenses to be incurred for deployment of the CISF personnel at Mahabodhi temple.
This is for the first time a religious shrine will be guarded by CISF, which is primarily responsible for the security of airports, nuclear installations and key government buildings among others.
