The NIA on 17 August got permission from a Delhi court to conduct a lie detector test on LeT terrorist Mohammed Naved, who was captured alive after an attack on a BSF convoy in Udhampur, Jammu and Kashmir earlier this month which had claimed the lives of two of its personnel.
Naved was produced before a court in the national capital where the anti-terror agency also secured permission to collect his DNA and voice samples.
The lie detector test on Naved, who is in NIA custody till August 24, will be carried out at 11 am on 18 August at the Central Forensic Science Laboratory in CGO complex.
During the in-camera proceedings, District Judge Amar Nath granted NIAs prayer for the polygraphy test after taking consent from Naved, a resident of Faislabad in Pakistan.
Naved gave his consent for the test in writing in Urdu.
"Keeping in view the seriousness and gravity of the offence I am of the considered opinion that polygraph test of accused is required to be conducted in the facts and circumstances of the instant case as fully explained in the application.
"Accordingly, I allow the present application permitting the NIA to take the accused to Central Forensic Science Laboratory, CGO Complex, Lodhi road, New Delhi on August 18 at 11 am for conducting polygraph test," the judge said.
There are many "loopholes", especially about his infiltration route and his association with certain people in the Kashmir Valley, a senior NIA official associated with the probe said, hoping the lie detector test will help unravel the truth.
Naved was overpowered by two young villagers who he had taken hostage after the attack on BSF personnel. The LeT terrorist's accomplice Mohammed Noman alias Momin was killed in retaliatory firing by the BSF.
The sources said DNA sample was being taken to be furnished to the Pakistani authorities if they expressed doubts about the militant's identity.
Naved was brought here from Jammu last week for carrying out scientific tests.
NIA Chief Sharad Kumar, who returned from his two-day visit to Jammu, had earlier said the agency has evidence of his Pakistani nationality and links to LeT, which trained him in use of arms and ammunition and for recruiting cadre for expansion of the terror group.
Naved has said he had undergone a refresher course for six weeks in Pakistan from march this year with 25 others before infiltrating Kashmir.
This was after he had undergone two training modules-- 'Daura-e-Aam' and 'Daura-e-Khas'. While the first module teaches LeT cadre physical fitness, mountaineering and use of small arms, in the second they are trained in using assault rifles and manufacturing small explosives.
