The protests outside New Delhi's Jamia Millia Islamia University on Thursday started out small and relatively low-key - another show of anger by students who oppose a citizenship law they say discriminates against Muslims.
But that quickly changed when a young man brandishing a rudimentary pistol appeared on the road between around 1,000 protesters and dozens of riot police facing them.
The injured man, Farooq, was in hospital receiving treatment for his wound, according to a friend with him who declined to be identified. The friend said Farooq was not able to answer questions.
Following the shooting, the number of protesters swelled to several thousand, and scuffles between them and several hundred police officers broke out.
