Rashid, along with many supporters of his Awami Ittehad Party, assembled near his residential quarters at Jawahar Nagar here and marched towards SHRC office, a party spokesman said.
He said as soon as the march reached near Zero Bridge, Rajbagh, police swung into action and detained Rashid as well as dozens of his supporters.
Rashid has been lodged at Police Station Rajbagh, the spokesman said.
A police official said the party had no permission to assemble or take out a march, so Rashid and some of his supporters were detained.
