Mumbai/UNI: The Mumbai Chhatrapati Shivaji Maharaj international airport has received an email threatening to blow up Terminal 2, with the sender demanding one million dollars in Bitcoin to prevent the blast, police said on Friday.

Following this, the local Sahar police station registered an offence, and the Mumbai police cyber crime cell was also informed.

"The airport received the threat email on Thursday in the feedback inbox of the airport, and its sender demanded 1 million dollars in bitcoin within 48 hours to prevent the blast at Terminal 2 of the airport," an official said.

The email reads, "This is a final warning to your airport. We will blast Terminal 2 in 48 hours unless one million US dollars in Bitcoin is transferred to the address. Another alert will be after 24 hours."

After receiving the email, an executive of the Mumbai airport approached the Sahar police station and lodged a complaint against the unidentified sender, he said.

Based on the complaint, an FIR under Indian Penal Code (IPC) sections 385 (putting a person in fear of injury in order to commit extortion) and 505 (1) (b) (statements made with intent to cause fear or alarm to the public or against the public tranquility) was registered against the unidentified person, he said.

The airport is operated by Mumbai International Airport Limited (MIAL).
