On December 17, Kumar was sentenced to life for the “remainder of his natural life” by the Delhi High Court.
The high court had on December 21 declined his plea to extend the time of his surrender by a month.
He has filed a petition in the Supreme Court challenging the conviction and the life sentence awarded by the high court.
Shortly before Kumar’s surrender two other convicts — former MLAs Kishan Khokhar and Mahender Yadav — too surrendered before the court.
The court had on December 17 also convicted former Congress councillor Balwan Khokhar, retired naval officer Captain Bhagmal and Girdhari Lal in the 1984-anti Sikh riots in the national capital.
The case in which they were convicted and sentenced relates to the killing of five Sikhs in Raj Nagar Part-I area of Palam Colony in southwest Delhi on November 1-2, 1984, and burning down of a gurudwara in Raj Nagar Part-II.
The riots had broken out after the assassination of then prime minister Indira Gandhi on October 31, 1984, by her two Sikh bodyguards.
