Delhi air pollution protestors display Maoist Madvi Hidma's posters

A protest over Delhi's toxic air crisis at the India Gate on Sunday sparked controversy after demonstrators were seen holding posters of slain Maoist commander Madvi Hidma, who was killed in a police encounter recently in Andhra Pradesh.

In the videos that are doing the rounds, a man can be seen holding a poster at the protest that read: "From Birsa Munda to Madvi Hidma, the struggle of our forests and environment will go on".

New agency ANI quoting Delhi police said, a protest, which was held at C Hexagon, India Gate, over pollution had the posters of Maoist commander Madvi Hidma on display and when demonstrators tried to block the road, the police tried to remove them. The police also said that the protestors sprayed pepper spray on the police personnel and tried to attack them.

Delhi Police registered an FIR against a group of more than 15 people protesting for allegedly using chilly spray on police personnel, obstructing official work and blocking the road.

According to Deputy Commissioner of Police (New Delhi) Devesh Kumar Mahla, this is the first time police personnel have encountered pepper spray during a crowd control operation. "This was very unusual. For the first time, protestors used chilly spray on officers managing traffic and law and order."
