Earlier, Umar Khalid was charged under the stringent Unlawful Activities (Prevention) Act (UAPA) in the case.
In the FIR, the police had claimed that the clashes were the result of a "premeditated conspiracy", which was allegedly hatched by Umar Khalid and two others.
Umar Khalid had allegedly given provocative speeches at two different places and appealed to people to come out on the streets and block roads during the visit of US President Donald Trump to spread the propaganda at the international level about how minorities are being treated in the country.
