But a passenger saw her. She tapped the person in front of her on the shoulder and say, "There's
a bum (流浪汉) in toilet. Tell the bus driver." The message was passing on from person to person.
But somewhere along the way, it was changed. The bus driver told that there was a bomb in the
toilet. He immediate stopped the bus and telephoned the police. When the police came, they told
the passengers to get off the bus or stay far away. Then they closed the highway. As a result, a
traffic jam of 15 mile long was soon caused. In the help of a dog, the police searched for two
hours. Of course they found no bomb.
