Security agencies are trying to ascertain the purpose of the visit of diplomat Madhuri Gupta, arrested on charges of spying for Pakistan, to Rajouri district, amid mounting suspicion that she was there to receive documents from a "source" but could not do so after her movements were detected by the Jammu and Kashmir Police.
Contrary to earlier reports that she had picked up a packet, the 53-year-old Gupta is understood to have failed to reach her contact from whom she had to take some documents pertaining to location of Army units.
However, sources said she could not get in touch with her contact because of heavy presence of police, paramilitary forces and other units of the Army which had gathered there in connection with an encounter that was going on after terrorists of Lashker-e-Taiba slipped in around the same time.
Gupta is understood to have told her interrogators that she could not meet her contact because of the heavy police presence in the area.
The IFS-B officer, who was posted in Indian Mission at Islamabad as Second Secretary in the Press and Information wing and arrested in April this year after she was called to Delhi, has named other officials who need to be investigated, the sources said.
An enquiry was on to ascertain the "source" of Gupta, the sources said.
The officer, who is at present in judicial custody, has been maintaining that certain classified documents were procured from within the Indian Mission in Islamabad.
The diplomat named Mubassar Rana, in his late 50's, and Jamshed, another Pakistan intelligence official in his early 30's, as her handlers.
Her stay in a border district of Jammu and Kashmir was being probed by security agencies who had grilled her over her contacts in Pakistan and the nature of documents supplied by her handlers.
She had driven to Sunderban in the border district of Rajouri in Jammu region during which she had toured the area extensively in her Pakistan-registered car between March 29 and April one this year.
