A commission of inquiry, which probed the 1984 anti-Sikh riots in Delhi, is understood to have recommended reinvestigation of cases against some Congress leaders including Sajjan Kumar while not blaming the entire party or the then prime minister Rajiv Gandhi for the incidents.

In a report to be submitted to the government on January 31, the Justice Nanavati Commission is believed to have said that though the violence that followed the assassination of Indira Gandhi was "organised and systematic" in several areas, the entire Congress apparatus cannot be held responsible for the acts of individual politicains, hooligans, depraved people and local gangs.

More than 3,000 Sikhs were killed in the violence that gripped Delhi from the night of October 31, 1984 lasting for three to four days.
