"We have registered a case under various sections of the Indian Penal Code against 13 named and nearly 400 unidentified activists of the BJP and the Congress at the Chakeri police station," DIG Kanpur Amitabh Yash said.
Efforts are being made to identify and arrest those involved in the violence, he said.
The police official further said, "None of the parties have yet registered a case, if they do so, we will take the required action and investigate the matter."
At least a dozen activists of the BJP and Congress were injured in the clash on Sunday.
Led by party leader Kalraj Mishra, BJP activists marched towards the Pokharpur residence of Jaiswal to stage a protest there. The protesting BJP activists, however, were stopped at a barricade set up by police about 200 metres from Jaiswal's residence.
After a heated argument, a clash broke out between the workers of both political parties. Police resorted to mild cane charge after heavy brickbatting from both sides.
"Two BJP MLAs Satyadeo Pachauri and Raghunandan Bhadoria and dozen of our workers were injured in the violence which triggered off on the behest of Congress leaders," party legislator Salil Vishnoi said.
Meanwhile, Jaiswal claimed that eight Congress activists were injured in the protest by the BJP.
