Congress leader Sajjan Kumar has been convicted by the Delhi High Court in the 1984 anti-sikh riots case. The court today reversed Kumar's acquittal by a lower court and sentenced him to life imprisonment. The congress man has been found guilty of criminal conspiracy, inciting riots and other charges by the court. The court ruling came on petitions challenging a trial court's order acquitting Sajjan Kumar. Kumar along with five others is accused of inciting riotous mobs to kill Sikhs in the aftermath of former Prime Minister Indira Gandhi's assassination in 1984.
