The Santacruz airport police is tracing the call records of the telephone number that was used to make a bomb hoax call to the Domestic airport on Thursday.
Investigations revealed the telephone was procured by producing fake documents.
The police had booked the unidentified accused for giving false information to a public servant, circulation of a false statement or rumour and under other relevant sections of the Aircraft Act.
After the new discovery, the sections of cheating and forgery have been added to the first insformation report.
The call, the police said, was traced to a Tata Indicom Walkie registered in the name of a Nerul-based businessman.
But, when the businessman was questioned, he said he had never applied for any such connection. He was questioned and let off.
When the police inquired the service provider about the details of the connection, the applicant’s address turned out to be fake.
“When we tried to trace the address submitted in the application form, we found that no such address existed,” said an officer.
“We are shortlisting the frequent callers and they will be questioned to find the user,” said Amitabh Gupta, additional commissioner of police, West Region.
On Thursday, minutes before the Kingfisher Airlines flight number IT 3149 was about to take off, the Central Industrial Security Force control room in the domestic terminal building received a call from a person who claimed to have overheard a conversation about a bomb in the flight.
This delayed the flight by more than five hours, disrupting the journey of 179 passengers on board to Lucknow from Mumbai.
