"I know karate, I'll kick your a**!" Hilarious moment feisty granny confronts drunk youth on bus

This is the hilarious moment a feisty grandmother attacked a drunken young man and tried to throw him off a bus.

The incident was filmed on a mobile phone by another passenger travelling in an unidentified city in Kazakhstan.

The video footage shows the pensioner, wearing traditional Kazakh clothing, suddenly confront the young man who appeared to be sitting minding his own business.

The woman starts wagging her finger in the face of the man, who was wearing jeans and a quilted jacket, and who turns away as if to ignore the woman.

That only seems to make her even more angry and she grabs hold of the man, dragging him out of his seat, shouting: "Get off the bus! I don't like drunks around me! Get off quickly!"

The young man can be heard yelling back at the woman: "Take your hands off me!" but she continues to push him away from her and kicks out at his legs.
