SHANGHAI: Local transport supervisors did not entrap a van driver while investigating illegal cab operations, according to urban management authorities in the Pudong New Area of Shanghai.

Authorities announced the judgment yesterday after an investigation on an alleged unlicensed cab operation by a 19-year-old driver named Sun Zhongjie last Wednesday.

The young man was so upset over the accusation that he cut off a piece of his little finger of his left hand to prove his innocence. He was sent to hospital immediately for surgery. But he said the doctor told him the finger may never recover its normal function.
