Security was increased at the Hotel Leela located near the city's international airport terminal following the receipt of two emails last week where the sender threatened to blow up the hotel, police said on Monday.
The emails were received by the hotel management on Friday and Saturday following which searches were carried out on both days by the Bomb Detection and Disposal Squad.
However, nothing suspicious was found on both occasions. In both e-mails, the sender threatened to blow up the hotel unless a sum of $1.3 lakh was not paid to him, Deputy Commissioner of Police (Zone X) Nisar Tamboli told PTI. "The identity of the sender is not revealed and neither is the place where the payment to be made mentioned," he said.
Despite the emails seeming like a hoax, police are not taking any chances and additional security has been provided at the hotel.
The Cyber Crime Cell of the Crime Branch is also carrying out parallel inquiries into the matter and officials said the emails are suspected to have been sent from abroad.
