The agitating Jats, demanding job quota for them, today served an ultimatum asking Haryana government to unconditionally release by tomorrow all those who had been taken into custody during the movement and threatened to intensify their stir if the demand was not met.
"The government should order release of all those Jat protesters who had been taken into custody two days ago," Jitender Chattar of All India Jat Aarakshan Sangarsh Samiti said.
He said they will give the government time till tomorrow afternoon to act after which they will intensify their stir and block all the roads to Delhi and other parts besides launching their agitation in other parts of the country.
Hisar, located 155 km from the national capital, had been virtually come under a siege of the protesters demanding OBC quota.
Meanwhile, Delhi-Hisar highway which had remained blocked on Wednesday opened to road traffic.
The district administration had yesterday ordered closure of all educational institutions for three days.
Security forces had conducted a flag march here last evening as Hisar remained on the boil. Uneasy calm prevailed in the district on Thursday.
At Garhi village near here, mobs smashed window panes of trucks triggering a major jam on national highway last evening. The protesters had placed tree trunks on roads at some places.
Jats are seeking reservation in government jobs for the community in OBC category and have accused Haryana Chief Minister Bhupinder Singh Hooda of "going back on promises" in this regard.
