Brave kidnappers

Today was the worst day ever. There is this rich family who live opposite my school. They got like 300,000 dollar cars and more in their house. While I was chatting with my friends outside my school after practicing for tomorrow's group singing competition, a kidnapping scene happened in front of my own two eyes. The mom of the rich family held her son's hand but she let go of her son's hand just to help him carry his bag. They were outside their mansion just about to get in. Suddenly, a brownish colored Proton car came and yanked the kid onto the car. I was so shocked till I couldn't even move. Chong Min Yuan, Merrylin and Yong Jia Min are my friends whom I was chatting with outside my school. Jia Min and I were too shocked to even move. Merrylin and Min Yuan got into action. Min Yuan remembered the car tag thing and Merrylin tried to see how the kidnappers looked like. The kidnappers were wearing helmets. I think some of this information might be helpful for the investigation.
