The trial of a Chinese artist charged with assaulting a police officer ended without a verdict Friday.
Artist and political activist Wu Yuren was charged with obstructing public affairs with violence relating to a confrontation with police when he visited a police station in May.
Wu said police beat him, while police say he hurt an officer's fingers.
Three months before the confrontation, Wu led a march of artists toward Tiananmen Square to protest mistreatment of artists by developers who want to tear down their studios for real estate profits.
Wu's supporters say police trumped up charges in revenge for his activism.
