It all happened Monday night in Sechelt, B.C., after the Sechelt band's two youth teams won first prize at a soccer tournament in Vancouver.
The parents said it is a community tradition to celebrate with a grand entrance by honking horns.
"They pepper sprayed him and when I went to say, 'What are you doing?' they turned around and pepper sprayed me and Kaden—quite a few times, actually."
Calvin Craigan, a former chief with the Sechelt band, told CBC Radio Tuesday that band members are "going to have a session with the RCMP" and demand an explanation.
