A man attempting to catch a bus was blinded by anger as he chased it into busy Nathan Road when it was stopping at a traffic light in the middle lane.
He tried to force open the door to board the bus by pressing the emergency door-open button outside of the bus.
But his effort was futile, and he started to yell foul language and went to the driver's side to continue scolding the driver.
The man's surprising action was posted on Facebook and received widespread criticism from users.
"Did he think he owned the bus?" one user commented.
Another remarked that he should have waited for the next bus instead of trying to board this one.
Kowloon Motor Bus strongly condemned the actions of the man involved yesterday and is considering appropriate follow-up actions.
The transport company emphasized that anyone disrupting operations, attempting to stop a bus or forcibly pressing the emergency exit button poses a serious danger to themselves, passengers and other road users.
