Sharjeel Usmani, the son of Assistant Professor Tariq Usmani of the AMU's Department of Geography, was picked by the Uttar Pradesh's anti-terrorist squad (ATS) sleuths from his uncle's house in Azamgarh on Wednesday and was subsequently produced in a court in Aligarh which remanded him in judicial custody, they said.
AMU spokesman Shafay Kidwai said that show cause notices have been issued to nine students for trying to hold an unauthorised gathering Thursday.
