The clashes broke out between the two groups of people when the Shobha Yatra procession was passing through the road just next to Kusal Cinema Hall, on the opposite side of which is a mosque.
As per several videos of the procession accessed by IANS, people can be seen wielding swords and chanting religious slogans just before the clashes broke out.
According to the FIR lodged at the Jahangirpuri police station, the Shobha Yatra procession was passing off peacefully, but at around 6 p.m., when they reached outside a mosque, the accused Anshar came there with his 4-5 associates and started arguing with the participants of Shobha Yatra.
The argument soon turned violent and both the sides started pelting stones at each other.
"I, Inspector Rajiv Ranjan Singh, tried to pacify the situation and separated the two groups, however, within some time, they again started pelting stones after which I informed the Police Control Room about the development," read the FIR.
Soon after this, more police force reached the spot along with senior officials, however, by that time the mob had turned completely violent. The mob pelted stones on the police force and also fired shots at them.
At least 8 policemen were injured.
To contain the situation and disperse the crowd, the police fired 40-50 tear gas shells. Amid the pandemonium, one scooty was torched and 5-6 cars were vandalised.
The Police normalised the situation with the help of paramilitary forces and at around 8 p.m. in the evening the situation was under control, yet tense.
Later, the area became the epicentre of the heavy police deployment, with the road, where the violent clashes took place, extensively barricaded from all sides.
