A German bus driver in the town of Lindau threatened to throw a 20-year-old woman off the bus because her cleavage was distracting him.

"Suddenly he stopped the bus," the woman, known as Debora C said in an interview with the Bild newspaper.

"He opened the door and shouted: 'Your cleavage is distracting me every time I look into my mirror and I can't concentrate on the traffic. If you don't sit somewhere else, I'm going to have to throw you off the bus'."

The woman said she changed seats, but was extremely embarrassed.

A spokesman for the bus company defended the driver's actions.

"The bus driver is allowed to do that and he did the right thing. A bus driver cannot be distracted because it's a danger to the safety of all the passengers," he said.
