"A group of 100-150 IYC and NSUI workers were marching on the streets on way to the PMO to demonstrate there but we detained them in front of Krishi Bhawan. Some of them dispersed after we disallowed them to go any further," a senior police official said.
While IYC is Congress's youth wing, National Students' Union of India (NSUI) is the party's student unit.
The protesters carrying IYC flags and placards shouted "anti-Modi" slogans and denounced police action on the students of JNU.
"We are also protesting against those who raised the alleged anti-national slogans, but why target the entire university for the mistake of a handful of students," a protester said before being taken away in the bus to the police station.
They were also protesting against the attack on students and teachers in Patiala House Court complex in police presence on Monday where the sedition case against JNUSU President Kanhaiya Kumar was to be heard.
