SHANGHAI: An investigation into an alleged illegal taxi operation, in which the driver claimed he was entrapped and cut off a finger to show his innocence, is now being supervised by legislators and media after a primary report aroused wide doubt.

The Pudong new area district government has formed a team of legislators, political advisers, lawyers and media to further investigate the incident, municipal government officials said yesterday afternoon.

The announcement was made soon after the district's city management and law enforcement bureau released a report on Tuesday, backing up its accusation that Sun Zhongjie ran an illegal cab operation on Oct 14.
