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.
They further said that the role of Inter-Services Intelligence and some terror organisations is needed to be probed in the case as he had also visited Pakistan.
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.
"About 100 rounds of ammunition were fired in the incident of jail break and two jail official were injured. He also snatched one official rifle from a jail official," the police said.
Mintoo was nabbed from a Delhi railway station, a day after he escaped with five other inmates from the jail.
The UP police last evening had arrested the alleged "mastermind" of the daring daylight jailbreak, Parminder Singh.
He was arrested from Kairana in Uttar Pradesh's Shamli district when the getaway vehicle -- a Toyota Fortuner -- was stopped at a police picket.
He had yesterday escaped along with five other prisoners in a sensational jailbreak after armed men in police uniform tricked the sentries into opening the gates and fled with the inmates while firing a hail of bullets.
Mintoo, who was wanted in ten terror cases, was arrested by the Punjab police after he was deported from Thailand in November 2014.
