Jundal was produced before District Judge I S Mehta in an in-chamber proceeding and the court extended his judicial custody till December 22 after National Investigation Agency (NIA) said its probe into the case is still going on, the
court sources said.
The NIA had lodged an FIR against Jundal following the unearthing of a Lashkar-e-Toiba's (LeT) conspiracy for terror strikes across the country.
The court had first remanded Jundal to judicial custody on October 20 after the NIA said he was not required for further custodial interrogation in connection with the case.
Gujarat ATS too had earlier taken Jundal's custody for questioning on his alleged role in the 2006 Karanawati Express train blast at Ahmedabad station. Jundal is alleged to be one of the main conspirators of the blast.
Prior to that, Jundal had been handed over to the ATS Mumbai after Delhi Police had said he was no longer required to be interrogated by it in the Jama Masjid attack case.
Mumbai ATS had secured his custody in connection with the 2006 Aurangabad arms haul case, the 26/11 Mumbai mayhem, the 2010 German bakery blast and the Nasik Academy attack.
