In a recent interview to a TV news channel, Gandhi had said that "some Congress men were probably involved in the 1984 anti-Sikh riots and they have been punished for it".
The protesters shouted anti-Congress slogans and held up black flags and placards, one of which read, "CBI should question Rahul Gandhi for Congress involvement in 1984 riots".
"We want justice. We want to know who were those people who were involved in the riots," said one of the protesters.
The 200-odd demonstrators marched towards the Congress headquarters and managed to break the first barricade. They were stopped, however, at the second barricade by police. Many of them were detained and taken to Tughlaq Road police station from where they were later released.
Congress leaders Jagdish Tytler and Sajjan Kumar are facing allegations of involvement in the riots which occurred in the aftermath of former Prime Minister Indira Gandhi's assassination on October 31, 1984.
So far, Delhi Police and CBI have held probes into the riots.
