SOMEONE threatens kids home alone

I was babysitting my little brothers and sisters. We just returned home from the carnival when SOMEONE came towards us. Since we were home alone and he has been violent on many occasions, I told my brothers and sisters to run in the house. SOMEONE started screaming because the little kids left their bicyles in front of our home. He started breaking the bikes so I took the video camera and started filming. You can see for yourself how he was threatening me, my little brothers and little sisters. My little sister called the police but they didn't even come. Tja, that's Rijnsburg!
