Chief Metropolitan Magistrate Vidya Prakash remanded Verma and his wife to judicial custody till September 28 after the CBI said it did not need them for further custodial interrogation.
The probe agency had registered a fresh case against the couple on August 28 under the Official Secrets Act on a defence ministry's complaint.
The duo were earlier remanded to the CBI custody for ten days on September 4 for their custodial interrogation and confrontation with incriminating documents collected so far as well as to ascertain the involvement of other persons, if any.
Verma's wife Anca also sought the court's permission to carry cosmetics inside jail. The court directed jail superintendent to consider her request as per the jail manual.
In an FIR registered on August 28, the CBI had said the Defence Ministry on June 6 had received a letter from Verma's business partner and Ganton Pvt Ltd's President C Edmond Allen with some documents annexed to it.
Upon verification, some of the documents were found to be "secret" and a complaint was made to the CBI by the ministry on August 27 following which a case under section 3 of the Official Secrets Act (passing sensitive information) and of criminal conspiracy under the Indian Penal Code was registered against Verma and his wife.
