Former Congress leader Sajjan Kumar surrendered before a Delhi court on Monday to serve the life sentence awarded to him by the Delhi High Court in connection with a 1984 anti-Sikh riots case.
He surrendered before Metropolitan Magistrate Aditi Garg.
The HC had set a deadline of December 31 for Kumar to surrender and on December 21 declined his plea to extend the time by a month.
Kumar (73) has filed a petition in the Supreme Court challenging the conviction and life sentence awarded to him by the high court on December 17.
After his conviction, Kumar resigned from the Congress party.
The case in which Kumar was convicted and sentenced relates to the killing of five Sikhs in Raj Nagar Part-I area in Palam Colony of 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.

Earlier in the day, former MLAs Kishan Khokhar and Mahender Yadav, who were also convicted in the same case, surrendered before the court to serve their 10-year jail term.
Media has not been allowed inside the courtroom.
The Delhi High Court on December 17 convicted and sentenced Kumar to life imprisonment for the "remainder of his natural life".
Besides Kumar, the others convicted in the case were former Congress councillor Balwan Khokhar, retired naval officer Captain Bhagmal and Girdhari Lal.
In its judgment, the high court had noted that over 2,700 Sikhs were killed in the national capital during the 1984 riots which was indeed a "carnage of unbelievable proportions".
It also said the riots were a "crime against humanity" perpetrated by those who enjoyed "political patronage" and aided by an "indifferent" law enforcement agency.
The high court had further said there has been a familiar pattern of mass killings since Partition, like in Mumbai in 1993, Gujarat in 2002 and Muzaffarnagar, Uttar Pradesh in 2013, and the "common" feature of each was the "targeting of minorities" with the attacks being "spearheaded by the dominant political actors, facilitated by law enforcement agencies".
The high court had set aside the trial court's 2010 verdict which had acquitted Kumar in the case.
