bomb threat received by the Rajiv Gandhi International (RGIA) Airport here by e-mail turned out to be a hoax, police said on Tuesday.
The airport's customer care section received the mail on Monday about the bomb threat and a thorough check was conducted by security personnel and no explosive or suspicious item was found and the threat turned out to be a hoax, they said.
Later, another message was received from a person, apologising for the previous one, saying his son was «mentally unsound» and that he had sent that message.
«We are verifying both the messages,» a police official said.
A case was registered at RGI Airport police station and further investigations were on.
