Police have arrested the two accused, identified as Mohit (24) and Abhay (25), both residents of East of Kailash and drivers by profession.
The victims, Mandeep Kalita and Arshad Akeel, were returning home from a local gymnasium in Maruti Swift car when a grey coloured Maruti Swift Dzire came from opposite side.
"Since it was a narrow road, Kalita asked the driver of the Dzire to give way to his car. The Dzire car driver, however, insisted that Kalita should reverse his vehicle and give way to their vehicle following which an argument sparked off between the two.
According to police, Kalita was hit on the left side of his head. The accused fled when some locals rushed to help the victims.
The injured were taken to AIIMS Trauma Center from where they were discharged later.
Police said that both the accused were under the influence of alcohol when they entered into a fight with the victims.
