The trio came to blows on the pavement and the victim was allegedly slashed in the arm.
The violence was halted by a plain clothes police officer who pulled out his gun on the knifeman.
But the suspect managed to escape during the altercation in Buenos Aires, Argentina yesterday (22 Jan).
The accompanying driver, who was not injured during the brawl, took the victim to the Mariano and Luciano de la Vega Hospital for treatment.
Jonatan, a passenger on the bus, said the row started when the suspect was told he couldn’t pay with cash.
The row erupted when the driver turned away the suspect for not having a SUBE card.
It is a contactless smart card system used in Argentina.
He offered money to a woman so he could use her SUBE card, according to the witness.
Jonatan continued: “He then said something and the driver turned on him.
“They started to fight.
“The driver who was travelling as a passenger then grabbed him by the neck and forced him against the window.
“They both ejected him and the guy walked in front of the bus and started throwing stones.
“The two drivers got off the bus and the row escalated on the pavement, ending with one of the drivers getting stabbed.”
The cop tried to stop the fight and pulled out his gun when the driver was allegedly knifed in the arm.
The violent scene was witnessed by crying children on the bus, as reported by Need To Know.
The police are currently trying to track down the suspect.
