India, April 16 -- A 61-year-old retired teacher was cheated of Rs.1.72 crore by cyber frauds posing as courier service agents and police officers in a scam operation that lasted more than a month.

The victim, a resident of Mahim, received a WhatsApp call, allegedly from a courier company. The caller claimed they had found the banned narcotic drug MDMA in her courier parcels and were carrying out a covert operation. They told her to stay absolutely mum, said a police officer from the Central Cyber police station.

The woman was given the phone number allegedly of a senior police officer whom she had to call. She was told her name had cropped in the Naresh Goyal case and she could be arrested, said the police officer.
