27-year-old Shaik, a resident of Pune, is considered a technical expert and an alleged key member of Indian Mujahideen and a hawala operator.
National Investigation Agency (NIA), which is probing the Dilsukhnagar twin blasts case, had filed a petition in the court of First Additional Metropolitan Sessions Judge, seeking directions to produce Shaik before the court, who has been named as an accused in the case, for the purpose of further investigation.
Eighteen persons were killed and 131 injured in the twin explosions that were triggered by powerful IEDs planted near Konark and Venkatadiri theatres in Dilsukhnagar, a crowded shopping area in the city, on February 21, 2013.
Shaik was arrested by the Delhi Police's special cell near Saharanpur railway station in Uttar Pradesh in September last year and is now under judicial custody and lodged in Tihar Jail.
