An IIT-Guwahati student has been detained after he allegedly pledged allegiance to ISIS in Assam's Hajo on Saturday. The fourth-year Biotechnology student recently claimed on a social media platform and emails that he intended to join the terror outfit and went missing from the IIT-Guwahati campus. This comes close on the heels of the arrest of the ISIS India head Haris Farooqi in Dhubri district after he allegedly crossed over from Bangladesh.
