The incident took place last night when two youths belonging to different communities had an argument over a mere sum of hundred rupees, which one person owed to another, they said.
The argument later worsened as people from the two parties took to the streets and indulged in stone-pelting which left at least 6 persons injured, SSP Omkar Singh said.
The injured have been admitted to a hospital.
Police resorted to lathicharge to disperse the men and bring situation under control.
