He claimed to be calling from the NIA and alleged that her Aadhaar card had been misused in a Rs.2.55 crore scam. He subsequently falsely claimed that a terrorist named 'Asif Fauji' had perpetrated the scam, using her name, and threatened her with arrest. The following day, Chandrabhan called her again on video.
