Top Lashkar-e-Tayiba bomb expert Abdul Karim Tunda, who has been admitted to the All India Institute of Medical Sciences for special cardiac care, was on Saturday sent to 14 days' judicial custody by a Delhi court.
A magistrate visited Tunda in hospital and remanded him to custody till September 7.
Tunda was scheduled to be produced before the court on Saturday after expiry of his four-day police custody.
He was admitted to AIIMS on Friday for special cardiac care.
70-year-old Tunda, who was arrested from the Indo-Nepal border last Friday, was admitted to Safdurjung hospital on August 22 after he complained of chest pain.
However, keeping in view the specialised care and security concerns, he was shifted to AIIMS the next day and admitted in the Intensive Cardiac Care Unit.
A Delhi court on August 20 had remanded Tunda to four day police custody for questioning him in connection with 37 bomb blast cases across the country.
The police had told the court that Tunda was a declared proclaimed offender in a case of recovery of explosive substances lodged in 1994 at south Delhi's Malviya Nagar police station under the provisions of stringent anti-terror law TADA.
