According to police, 25-year-old cabbie had stopped at the Summerhill Hotel in Reservoir, where five people were asking for a ride on Saturday night, Jan 16.
The driver refused to carry them all, because of the car's legal capacity and instead only picked up a man and a woman from the group.
Police said the woman became angry at the driver for refusing to take her friends with them. The man then punched him as he pulled over on Plenty Road and continued to assault him as the couple climbed out of the cab.
Police have asked witnesses to come forward to help them catch those who bashed the driver. They also released images of the couple involved in the attack.
The victim told police he called an ambulance and was treated for facial injuries at the Northern Hospital after the assault.
Police came out with a statement on it only Tuesday night, Jan 19. They said there is no evidence that the attack was racially motivated.
The incident was the fifth such attack on Indian cabbies within a week.
