Lucknow, Feb 25 (IANS): A dozen districts in Uttar Pradesh have been put on high alert in view of violence in Delhi.

Districts witnessing anti-CAA protests have been asked to impose prohibitory orders under Section 144 'wherever required' and ensure extra vigil at the protest sites.

The 'sensitive' districts, according to police sources, are Lucknow, Kanpur, Prayagraj, Meerut, Saharanpur, Aligarh and Varanasi among others.

"We have increased police presence in all districts on the Delhi-Haryana borders and the anti-CAA protest sites have also been put under scanner. We are keeping a close vigil on the situation and intelligence agencies have also been asked to give inputs on the developments. We will not allow miscreants to create trouble in UP," said a senior police official.

Extra forces have been deployed at the Clock Tower protest site which witnessed clashes on Sunday when an unidentified person opened fire.

The death of a girl at the protest site has also sent temperatures soaring. The girl died after she fell ill while sitting at the site during rains last week.

Meanwhile, Chief Minister Yogi Adityanath has also asked top civil and police officials to remain alert about the situation in the state.
