The protesters were detained yesterday when they reached Kilazfargarh village on the Rohtak border as they did not have requisite permission, the police said.
"Reservation is our right," the leader of the protesters, Devi Das, said before being taken into custody.
"We will not rest until we get what we deserve. We are staging a peaceful protest. Despite that, the police have detained us," he said.
The group has been staging a sit-in in Jind for the last 171 days to press for reservation for the community.
"If they had permission, we would have allowed them to enter Rohtak," Kumar said.
Shah yesterday began his Haryana visit from Bahadurgarh and is slated to hold a series of meetings and review works undertaken by the M L Khattar government during his three-day stay.
