Arshad, who was lodged in Kolkata jail in connection with the shoe baron Partha Roy Burman kidnapping case of 2001, was arrested here in the case after he was produced before the court in pursuance to production warrant issued against him.
He was today produced before Additional Sessions Judge Reetesh Singh after expiry of police custody and the Special Cell of Delhi Police told the court that he was not required for any further custodial interrogation in the case.
After hearing the submissions of special cell, the court remanded Arshad to judicial custody and asked the police to send him back to Kolkata.
On August 13, the court had remanded Arshad to police custody till today after the special cell had said that he was required to be quizzed to unearth the whole conspiracy and to know about the "penetration of LeT in Delhi and other parts of India".
The police had earlier filed its charge sheet in the case against accused Mohd Rashid and Mohd Shahid who were arrested in December last year from Haryana's Mewat region.
With their arrest, police had claimed to have unearthed a terror module of LeT which was at an "advanced stage" of planning a major strike in Delhi.
