Sajjan Kumar (born on September 23, 1945) is an Indian politician belonging to the Indian National Congress party. He was a member of 14th Lok Sabha representing Outer Delhi constituency. He was sworn as Delhi Councillor by prominent social activist Guru Radha Kishan in 1977 and was first elected to the Municipal Corporation of Delhi at a time when only few congressman were able to manage a win in Delhi.
Kumar is one of the most noted accused in connection with the 1984 sikh riots. According to the eyewitnesses, he had incited mobs to kill Sikhs in the aftermath of Indira Gandhi's assassination.
A prosecutor of the Central Bureau of Investigation (CBI) in 2012 had told a Delhi court that riots targeting the Sikhs had the "patronage" of Sajjan Kumar. Kumar had organised anti-Sikh riots, the CBI alleged.
In April 2013, Kumar was acquitted by the Karkardooma district court in Delhi, while five others were convicted, which lead to protests.
In August 2013, the Delhi High Court accepted an appeal filed by the CBI against Kumar's previous acquittal by a lower court. The CBI had stated that the trial court "erred in acquitting Sajjan Kumar as he had instigated the mob during the riots".
Kumar was sentenced to life imprisonment by Delhi High Court on December 17, 2018 for his role in the 1984 Sikh riots.
