The Chinese consulate is shown Friday April 30, 2010 in Houston. Three Houston police officers have been restricted to desk duty after they followed a Chinese diplomat into the parking garage of the Chinese Consulate, arrested the man and injured him, the Houston mayor said. Mayor Annise Parker said in a statement that the officers’ duties will remain limited pending an investigation into how Chinese diplomat Yu Boren was injured last Saturday. (AP Photo/Steve Campbell)
