LeT bomb expert Abdul Karim Tunda, arrested in a 1997 bomb blast case, was on Thursday sent back to judicial custody by a Delhi court after he was produced in court by the Hyderabad Police.
Additional Sessions Judge Dharmesh Sharma sent Tunda to Tihar jail till November 7.
Tunda was handed over to the Hyderabad Police following its plea seeking his custody in connection with a production warrant issued against him by a court in Nampally in Hyderabad in a 1998 case lodged against him and others. The Delhi court sent him back to jail after the Hyderabad Police said they did not require him for further custodial interrogation.
70-year-old Tunda was arrested from the Indo-Nepal border at Banbasa on August 16.
He was earlier remanded in police custody for questioning in connection with 37 bomb blast cases across the country.
Tunda is one of the 20 terrorists whom India had asked the Pakistan government to hand over after the 26/11 Mumbai terror attacks. He is the first on the list to be arrested.
