Additional Sessions Judge Reetesh Singh sent Mintoo to custody till December 5 after Delhi Police sought seven days' remand to interrogate him.
"I am satisfied that custodial interrogation is required to unearth the conspiracy in the case. The accused is sent to police custody till December 5," the judge said.
While seeking his remand, the police said that they needed the custody of the dreaded terrorist to know about the role of "insiders and outsiders" who assisted him and five others in fleeing from Nabha jail in Patiala.
One loaded pistol and six live cartridges were recovered from his possession, the police said, adding that he was earlier a member of Babbar Khalsa International and later floated his own group.
