Wellington, Nov 14 (IANS): A seriously injured Indian-origin cab driver in New Zealand is recovering from emergency surgery following a vicious, unprovoked attack in the North Island city of Hamilton, a media report said Friday.

The 45-year-old victim said that he had no idea why a stranger knocked his teeth out as he sat in his cab Tuesday, the .

"The attack on me was shocking," he said.

"I needed medical and dental treatment and it's shaken not just me, but my wife and three children as well."

He was punched repeatedly in the face and mouth by a man who then demanded cash.

The victim is now begging anyone with information on his attacker's identity to contact police.

"Because of my injuries I haven't been able to return to work and I would be really grateful for any assistance the public can give to police to find the person who attacked me."

An investigating official said that the victim was sitting in the taxi when the assault began.

He did not believe it was a racist attack.
