New Delhi: Dr Kafeel Khan, who was heavily criticised for his inflammatory speech at Aligarh Muslim University (AMU), was on Friday booked under the National Security Act (NSA) by the Uttar Pradesh government, headed by Chief Minister Yogi Adityanath.

Khan, a suspended lecturer-cum-paediatrician was arrested on January 29 by UP Police for delivering a controversial speech at the prestigious AMU during the anti-Citizenship Amendment Act on December 12. He was granted bail on Monday, earlier this week, but was still held at the Mathura jail.

His brother had countered a PTI report that stated he was released and charged that the jail authorities did not honour the court’s order and kept him in custody despite being granted bail.

Dr Kafeel Khan first grabbed spotlight in August 2017 when he was entangled in a controversy in connection to the death of 60 children in less than a week at the BRD Medical College in Gorakhpur. Reports were that the children’s oxygen supply was cut off over a disruption caused by unpaid bills to its vendors.

Khan was subsequently suspended and jailed for nearly a year. He was granted bail in April 2018 by Allahabad High Court after no evidence was found on negligence on his part.
