Link magistrate Geetanjali postponed Gupta's judicial custody till Jul 24 as the chief metropolitan magistrate was unavailable. So the court is likely to bring the charge sheet on Jul 24.
The Delhi Police has handed the charge sheet of the IFS Grade-B officer for passing secret information to Pakistan government.
The charge-sheet and annexures filed had sought the prosecution of the officer under various provisions of the official secrets act and the Indian Penal Code.
The probe agency, citing Gupta's false e-mails in the charge-sheet, claimed that she used to pass on information to Pakistan's intelligence agencies through her close friend, Jamshed, whom she had planned to marry and Mubshar Raza Rana.
"The contents of an email showed that she was in love with Jim (Jamshed). Both had planned to get married. It is further very clear from the content that Jim is a Pakistani. The motive is clear and established from the email," said the charge-sheet.
The police, had claimed that she got in touch with Rana and Jamshed after she was introduced by Javed Rashid, a journalist of Jung newspaper.
Rana created an email ID for her asking her to send information through given email ID, and also referring to the recovery of two mobile phones from her possession with sim card and a Blackberry having a Pakistani sim card, said the police. Now police has received 30 witnesses to charges against Gupta.
Earlier, when Gupta was arrested in April, police had alleged that she was paid Rs one lakh for allegedly passing classified information to ISI agents.
Gupta,53, who was appointed as second secretary, press and information at the Indian High Commission in Islamabad, was arrested on April 22 by the Delhi police's special cell on the charges of revealing secret information to Pakistani officials.
