According to Zeenews report, the ruling AAP has put up posters in parts of the city, claiming to bring to justice the perpetrators behind the riots.
The posters read: "1984 ke Sikh katleaam ka ab hoga insaaf (justice will now be done for the massacre of Sikhs in 1984)".
The posters carry Delhi Chief Minister Arvind Kejriwal's photo and his name.
The posters surfaced after the Kejriwal government announced its move to set up a Special Investigation Team (SIT) to probe the 1984 riots cases.
Shortly after the Congress vice president Rahul Gandhi admitted some party members' involvement in the violence during an interview, the AAP, BJP and the Akali Dal had demanded an SIT probe into the 1984 anti-Sikh riots in Delhi.
Kejriwal said the party promised to demand an SIT probe into the riots in its election manifesto and was fulfilling the promise.
