stolen 2010 Supercycle

The bike was stolen when i was riding it around the road at front of my cousins house. I went inside for about 3 minutes my grandfather came and told me that my bike has been gone. He says he saw a black guy was riding a bike fast on the side walk and jumped into the road and passed him. My grand father cant see well so he didn't see who he actually was. It was stolen at Vivians Crescent brampton Ontario.
