My name is Tina. In the morning, I saw a man going to the bank when I was going home. Then I saw the man come out with a black bag.  I thought the man must be bad.  Later on, I  saw a bank teller come out from the bank and asked me “do u see a man?”  I said, “Yes, he carried a black bag and went away!” The bank teller said, “He is a robber. We should call 999 and catch him!” 

Five minutes later, the policemen arrived and looked for the robber.  Finally, they found the robber and grabbed him back to the police station.   I felt very happy.
