out of the blue in front of me was a man dressed in black. he had a black mask, black jacket, black pants, black gloves. He pulled out a gun and pointed it at me. I realized this is a mugging. the offender is not threatened and I was silent. I was very scared. I pulled out the money, phone, clock and gave him. and like a bolt from the blue police appeared and grabbed the perpetrator. they drew up at the crime scene criminal case. it turned out, I helped identify a terrible and dangerous thief. I was glad to help.
