SP (City) Aakash Tomar said unruly vendors of the 'Sunday flea market' were trying to block the road at Hapur Chungi area.
The police had to use mild lathicharge to disperse the crowd, he said.
The street vendors of the weekly flea market have alleged that the shop owners of the area have created hindrances in their craft, rendering them jobless.
On the other hand, the shop owners associated with the Navyug Market Vyapar Mandal (NMVM), including residents of nearby colonies of Bihari Nagar and Chandra Puri, have claimed the flea market occupies a large area of the market and hinders the vehicular flow in the area, especially in cases of emergency.
