On Qingming (Tomb Sweeping Day, April 4, 2012), police in Beijing detained many of the petitioners from Shanghai and other places in China who visited Beijing’s Babaoshan Cemetery to pay their respects at various graves. At another Beijing cemetery, five petitioners were detained when they tried to visit the grave of Yang Jia, a young man executed for killing several police officers and regarded by many as a folk hero who fought against police brutality. The police also detained Beijinger Li Xuehui, who was trying to deliver food to the detainees.
