New Delhi, Dec. 14 -- The National Investigation Agency (NIA) is likely to file a charge sheet in the April 22 Pahalgam terror attack next week, when the 180-day deadline since the first arrests ends, people familiar with the development said on Saturday. Two Pahalgam locals - Bashir Ahmad Jothar and Parvez Ahmad Jothar - were arrested on June 22 this year, nearly two months after terrorists killed 25 tourists and a pony operator at Baisaran meadow in Pahalgam. The two arrested were accused of harbouring and assisting the three Pakistani terrorists - Suleiman Shah, Hamza Afghani alias Afghan and Jibran - involved in the attack. In October, NIA sought 45 more days from a Jammu court beyond stipulated 90-day time to complete the probe, which was allowed by the court on September 18. "The tentative 180-day deadline for filing the charge sheet under Unlawful Activities Prevention Act (UAPA) since the day of arrest ends on December 18, by when we should be able to file the charge sheet in Pahalgam terror attack," said an officer, who asked not to be named. As earlier reported by HT in October, the Lashkar-e-Taiba (LeT) and its proxy The Resistance Front will likely be named in the charge sheet. On July 29, Union home minister Amit Shah confirmed in Parliament that the terrorists were from Pakistan and belonged to LeT. According to the officer quoted above, during its probe over the last over six months, NIA has recovered some Pakistani contact numbers from the phone numbers of the Jothars, which are crucial to unearth the entire conspiracy. "During investigation, names of some more suspects and additional clues have surfaced which are required to be substantiated," NIA told a court in September....
