Ismath and Abdullah Rahman, arrested by the Special Investigation Team police on November 1, were produced before a magistrate court yesterday which extended their remand till December 2.
Police have said the two, residents of the city, had provided their vehicles to "Police" Fakruddin and Bilal Mallick, former hardcore members of banned terrorist outfit Al-Umma, identified as the brain behind the plot to attack Advani's convoy. Fakruddin and Mallick are still at large.
The powerful pipe bomb was unearthed from under a bridge and defused on October 27 at Alampatti village, about 30 km from here, on the route of Advani's Jan Chetna Yatra.
