A horrible experience

It was the most horrible experience that I had ever had. Last month, when I was on my way home after school, I found that someone was following me. At the beginning, I did not care about it, but when I started to run, he ran after me and caught me at the arm. I was scared so I began to scream as loud as I could. And I also dialed to the police station secretly at the same time. Unfortunately, the man found that and he was so angry that he tried to tie me up but I struggled intensely. Suddenly, the police car arrived, and the man was caught by the police. After this event, I became more carefully and prepared a whistle with me when I had to go home alone.
