SHANGHAI: A driver who sued local traffic police for legal recognition of his innocence said he has received threats pressing him to withdraw the case.

Zhang Hui, a white-collar worker in Shanghai, was fined 10,000 yuan ($1,470) in September by local traffic management authorities of the Minhang district for operating an illegal cab service.

Zhang immediately brought the local traffic police to court, alleging that the police obtained evidence against him by adopting an illegal entrapment scheme.
