The Aligarh Muslim University has decided to file a complaint against the Uttar Pradesh police over "excesses" committed during their crackdown on students protesting against the Citizenship Amendment Act last month. Police had entered the campus with the Vice Chancellor's permission on December 15, after an attempt to prevent students from taking out a protest march in solidarity with their counterparts from Delhi's Jamia Millia University resulted in violence at its gates. The Jamia campus had witnessed violence during a protest against the controversial law earlier that day.
