"Last night in Vancouver seven participants in a casserole solidarity demonstration were detained and/or arrested by the Vancouver Police Department (VPD).

"They were taken down violently, roughed up, cuffed, searched and detained for hours. They were not informed as to why they were being arrested, or what if any laws they may have broken. They were, in short, denied most of their Charter rights."
