There was a robbery at City Central Bank last yesterday afternoon. Two men entered the bank at about 4 p.m. and told the bank teller on duty to give them $ 1,000,000. The robbers were carrying guns（枪） and wearing black masks（面具） to cover their faces. The robbers told all the customers （顾客）in the bank to lie down on the floor. Witnesses （证人）said that everyone in the bank was very frightened and did what the robbers told them.
The teller agreed to give them the money but told them they’d have to wait a few minutes. She said the bank manager would have to get the money out of the safety. As the robbers were waiting for the money. the teller tried to press an alarm button(按警报按钮) that was hidden under the counter. It was a silent alarm, so the robbers didn’t realize it had been set off.
Just as the manager arrived with the money, ten police officers entered the bank. The robbers were very surprised that the officers caught them easily. The robbers are now in custody（拘留） , and will appear in court next week.
Police congratulated Miss Alston , the bank teller , on brave act. The bank manager said that he would give Miss Alston a week’s vacation to thank her.
