Dr Kafeel Khan, the Uttar Pradesh doctor who was jailed after the death of over 60 children at a government hospital in 2017, was arrested in Mumbai late Wednesday night by Uttar Pradesh Police. He is accused of giving a provocative speech on the Citizenship (Amendment) Act or CAA at a talk at the Aligarh Muslim University last month. Dr Khan was arrested after a First Information Report (FIR) was registered against him in December, sources say.
