The Supreme Court on Monday upheld the death sentence awarded to three AIADMK workers in connection with the 2000 Dharmapuri bus burning case in which three college girls were charred to death. A bench comprising Justices G.S. Singhvi and B.S. Chauhan confirmed the death sentence awarded by the Madras High Court in 2007. The trial court had also held the three workers guilty and awarded capital punishment. Twenty-five other persons were given punishments ranging from two months to two years imprisonment in the case.
