An Australian Punjabi Taxi driver who allegedly beat a passenger with an iron bar has appeared in court for the first time.

Maninder Singh, 26, appeared in Port Adelaide Magistrates Court Wednesday Dec.5 charged with one count of aggravated assault with a weapon and one count of theft.

Singh, of Campbelltown, allegedly became involved in an argument with a passenger he picked up at Alberton on October 28, after the man complained Singh was driving in the wrong direction.

Singh allegedly stopped the taxi at Beverley and hit the man several times in the head with a metal pole.

The victim was knocked unconscious and treated for head injuries at Royal Adelaide Hospital.

Singh, who shielded his face as he walked to and from court, was not required to enter a plea and remanded on continuing bail to face court again in January.
