Students, journalists and teachers protested in the Indian capital on Tuesday after a student union leader's arrest and subsequent violence by Hindu nationalists.

The uproar has once again sparked allegations that Prime Minister Narendra Modi's government and his Hindu nationalist Bharatiya Janata Party are displaying intolerance and cracking down on political dissent in the name of patriotism.

Police cordons blocked right-wing Hindus from entering the campus of Jawaharlal Nehru University, where thousands of students have been protesting for days.
