Doshi, who is based at Reliance Centre in Ballard Estate, replied that no such request had been forwarded.
Doshi and the rest of Ambani's staff panicked when they received another communication from the I-T Department on July 12, informing that the password had been changed again.
Suspecting corporate hacking and espionage, ADAG approached Crime Branch, following which Joint Commissioner of Police (Crime) Himanshu Roy directed the Crime Branch Cyber Crime Cell to investigate.
Mumbai police took around 25 days to trace the area from where the account was hacked into, and a case was registered under IT Act on September 7.
"Investigation led us to the Chikkadpally firm of Manoj Daga, and a team headed by Inspector Mukund Pawar confiscated the server on which folders containing details of Ambani's I-T returns were stored. Daga wasn't aware of the crime, as he had been out of Hyderabad for more than a month after his father's death," a Crime Branch source said.
The cops found that besides Daga, only his niece, who is doing her articleship at the firm, had access to the server.
"We confronted her with evidence, following which she confessed to accessing Anil Ambani's tax returns details," a Crime Branch officer said.
Roy said, "We have seized a large amount of electronic evidence, and will take a call on further action after thoroughly evaluating the evidence"
The girl accessed Anil Ambani's PAN card number from the Income-Tax Department website by providing basic details such as his birth date, mother's name, etc.
She then logged on the Income-Tax Department's portal for filing e-returns (incometaxindiaefiling. gov.in) using an email account by the name khurana.jeet.2001@gmail.com, and used Anil Ambani's PAN card number to reset the password of his account.
Once the I-T Department sent the password to the gmail account listed by the accused, she accessed the details of his tax returns.
"It is surprising that the I-T Department didn't bother to verify the authenticity of the password change request, and sent the new password to an unknown email ID.
"The accused was nailed after she created folders containing details of Ambani's I-T returns using the firm's server," a Crime Branch officer said.
