Security was tightened for RBI Governor Raghuram Rajan following a death threat purportedly from the Islamic State (IS) terror group, an official said on Thursday.
The threat, received via an e-mail on Rajan's official ID, came around three weeks ago after which the Reserve Bank of India (RBI) informed the Mumbai Police crime branch.
Rajan is out of India, but police are taking no chance and security was tightened at the iconic RBI headquarters here.
Efforts are on by the Cyber Cell to track down the e-mail's origin and its credibility.
The sender claimed that he had been given a contract to eliminate Rajan, but was open to negotiations on the issue. This has both perplexed police officers and also made them wonder about the genuineness of the threat.
