The National Investigation Agency (NIA) has released sketches of two Pakistani terrorists who sneaked into India along with Mohammed Naveed alias Usman – the Lashkar-e-Taiba (LeT) operative who was caught after he attacked a BSF convoy at Narsu Nallah in Jammu & Kashmir's Udhampur district on 5 August.

The sketches were drawn on the basis of Naveed's description of the duo, identified as Zargham alias Mohammad Bhai and Abu Okasha. While Zargham is around 40-year-old, Abu is said to be a teen, barely 18-year-old. Both are the residents of Khyber Pakhtunkhwa in Pakistan, according to an IBNLive report.

The NIA has announced a reward of Rs 5 lakh each on the two absconding terrorists.

"Any person from public, who will give any fruitful reliable information about the whereabouts of these terrorists, leading to their arrest will be rewarded as mentioned above. The identity of the informer will be kept secret," NIA press release said.

At least four terrorists had entered India in June. Naveed and his accomplice Noman were assigned the task to attack security forces. While Noman was killed in the encounter with the BSF jawans, Naveed was captured with the help of three civilians. However, the security forces have failed to track the location of the other two terrorists.

The NIA on Monday sought permission of a Delhi court to conduct a polygraph test on Naveed. The court had asked the agency to conduct the test at Central Forensic Science Laboratory in Lodhi Road at 11 am on 18 August.

"Keeping in view the seriousness and gravity of the offence, I am of considered opinion that the polygraph test of the accused Mohammed Naveed is required to be conducted in the facts and circumstances of the instant case as fully explained in the application," the judge said as reported by IANS.

The NIA had requested for the lie-detector test as Naveed was inconsistent in his statement on various occasions. He had given his consent for the test in writing in Urdu.
