Colaba and Bandra police have registered separate FIRs in connection with the threat call received at the Taj Mahal Palace Hotel last week. Doctors and nurses working on the frontline in the BMC hospitals have been staying at the iconic Taj hotel for the past three months.

A person, identifying himself as Sultan from Pakistan and claiming to be a member of terrorist organisation Lashkar-e-Taiba, called the Taj hotel at 12.35 am on June 30, threatening to strike again. He disconnected the call and dialled again, 4 minutes later, and the telephone operator forwarded the call to the hotel's security department.
