A video of Indian policemen beating Muslim women advocating for wearing the hijab in school revived the controversy on Wednesday.
The footage has been circulating on social media, and was broadcast by the local NDTV channel.
It shows a group of women with their faces covered being approached by police before being struck by long bamboo sticks.
The incident occurred Sunday in Ghaziabad, a city in the northern state of Uttar Pradesh bordering New Delhi.
It has sparked controversy over the use of force against protesters, leading to authorities justifying police actions.
The debate over the wearing of hijab began Dec. 28 when the state government of Karnataka banned girls with headscarves from attending schools.
The Karnataka High Court has blocked students from wearing religious garments until it makes a final ruling on the matter.
