BEIJING, Aug. 2 (Xinhua) -- A book based on the true story of a high-profile railway gang crackdown in China in the 1980s was published on Friday.

The Chinese-language "Decoding China's No.1 Railway Crime Case" takes readers back to a time when railway theft and robbery were rampant in China. In extreme cases, gang members even robbed firearms from railway police.

A 30-strong-member police squad was then formed to address the problem. The squad members made a lot of personal sacrifices and pooled their strength and wisdom to knock out one gang after another, restoring peace to railway cabins.

The author, Wang Zhonggang, is an expert on criminal investigation. In his 43-year police career, Wang has won numerous merit citations for his performance.
