A case was registered after an unidentified person sent an email to the Mumbai International Airport Limited (MIAL) threatening to blow up a flight of IndiGo airline, a Mumbai police official said on Sunday.
The email threat, which was received on Saturday night, turned out to be a hoax after nothing suspicious was found post a thorough check of the aircraft, the Sahar police station official said.
The email had a sentence that read "I will blow up flight 6E 6045", he said, adding that an FIR has been registered under Indian Penal Code section 506B (issuing death threat) and other offences.
