On October 16, 2007, the inspection squad of the Zhabei Branch went to Beijing to visit Yang Jia and his mother, Wang Jingmei. Yang Jia demanded that the police pay 10,000 yuan in compensation. The inspection squad did not agree, nor did it discipline any police officer.
After dawn on October 6, 2007, Yang Jia left the police station and took a train back to Beijing. From that day on, he repeatedly filed complaints through petition letters and emails with the Shanghai Public Security Bureau and the inspection department of the Zhabei Branch, demanding the dismissal of the officers involved, compensation for emotional distress, and reimbursement of telephone charges. After investigation, the inspection detachment of the Zhabei Branch concluded that the officers' law enforcement was not improper, and the complaint received no apology whatsoever.
