According to court sources, Ali was produced before District Judge Amar Nath from Tihar Central Jail, and during in-camera proceedings, the National Investigation Agency (NIA) moved an application seeking extension of judicial custody for the accused.
The NIA, in a twist to the turmoil in Kashmir, had cited Ali's confessional video to claim that the ongoing unrest in the Valley was being orchestrated by Pakistan-based LeT which had played a major role in fuelling the unrest, triggered by the encounter killing of a militant leader.
NIA had earlier told the court that along with his associates, Ali had planned terror strikes to "destabilise the security and sovereignty" of India.
A fourth-class dropout Ali, who hails from Jahama village of Raiwind in Lahore, was arrested from village Yahama in Mawar area of Qalamabad, Handwara, in North Kashmir on July 25. The army had claimed to have recovered three AK-47 rifles, two pistols and Indian Rs 23,000 from his possession.
