Sun Zhongjie, from Henan province, is overcome with emotion in Shanghai after hearing that the authorities had cleared his name following a high-profile accusation that he was the operator of an illegal taxi, in Shanghai, October 26, 2009.

Sun cut off his finger to demonstrate his innocence in October last year after he was accused of operating an unlicensed taxi by the local traffic police in Pudong district in Shanghai.

A series of official investigations were then set off looking into the validity of the practice of entrapment. Sun cleared his name later that month when the district government apologized to him and admitted the illegal entrapment. The case exposed controversial police tactics to ensnare unlicensed taxi drivers. [Photo/CFP]
