The incident occurred when some of the policemen posted in wireless wing allegedly threw empty beer bottles at a house in Adarsh Nagar and broke windscreens of some vehicles parked outside the houses.
Locals opposed this which led to the clash in the area, police said.
The locals alleged that the policemen of the wireless wing often create nuisance in the area.
Two separate FIRs have been registered by both the parties against each other and the matter is being investigated, SHO of the Adarsh nagar police station Brajbhushan Agrawal said.
