Thousands of people have taken to the streets in the Indian capital Delhi as part of the cockroach protests, calling for educational reforms and the resignation of a government minister.
BBC Verify has been analysing videos from across the capital, which show security officers firing so-called pellet guns towards protesters.
The Central Reserve Police Force didn't respond to our questions about the use of pellet guns and the injuries protesters appeared to sustain.
It told media in India it was premature to comment and it was looking into events. Merlyn Thomas and Shruti Menon reports.
