72-year-old Tunda, who is currently in judicial custody in connection with various terror-related cases, is one of the 20 terrorists whom India had asked Pakistan government to hand over after the 26/11 Mumbai attacks.
Tunda was arrested from Indo-Nepal border at Banbasa on August 16. He is suspected to be involved in 40 blast cases across the country.
Zakaria, Allauddin and Bashiruddin were lodged in separate jails in West Bengal in connection with cases lodged against them there and they were produced before the court here after production warrants were issued against them.
Earlier, the police had also filed a charge sheet against Tunda in connection with the 1997 Sadar Bazar blasts case in which several persons were injured.
In its supplementary charge sheet, the special cell had charged Tunda with offences under sections 324 (voluntarily causing hurt by dangerous weapon), 307 (attempt to murder) and 120-B (criminal conspiracy) of the IPC.
The police had said Tunda was part of the conspiracy which led to two bomb blasts, one in Sadar Bazar and other in Qutab Road here, on October 1, 1997 in which several people were injured.
