The Reserve Bank of India (RBI), HDFC Bank and ICICI Bank on Tuesday received 11 bomb threats in Mumbai but the police found no suspicious object at these locations.

The e-mail was sent on the RBI Governor’s email id at around 10.50 am threatening bomb blasts at the RBI new Central Office building, Fort, HDFC House in Churchgate and ICICI Bank Tower in Bandra-Kurla Complex at 1:30 pm.

The e-mail, sent from the id khilafat.india@gmail.com, sought the resignation of Union Finance Minister Nirmala Sitharaman and RBI Governor Shaktikanta Das from their posts immediately and release a full statement about the disclosure of the ‘banking scam’.

A case has been registered and the probe is underway, police said.

"11 bombs are planted at different locations in Mumbai and explosions will take place at 1.30 pm at the RBI new Central Office building, Fort, HDFC House in Churchgate, and ICICI Bank Tower in Bandra-Kurla Complex. All the 11 bombs will blast one by one (sic)," the mail said.

Police conducted searches at all the locations mentioned in the e-mail with Bomb Detection and Disposal (BDDS) personnel, but nothing suspicious was found at these spots, a police official told PTI.

He said a case has been registered against an unidentified person on the complaint of the RBI head guard under various sections of the Indian Penal Code including 505-1 b (Making or circulating a false alarm or warning as to disaster or its severity or magnitude, leading to panic), 502-2 (Statements conducting public mischief) and 506- 2 (Criminal intimidation).

Further investigation is underway, the official said.
