China: Police chiefs investigated

At least six district police chiefs are being investigated on suspicion of protecting local gangs in a major crackdown on crime in Chongqing, China.

The six are suspected of being "protective umbrellas" for gangs.

Local media have reported that the gangs were involved in illegal casinos, loan sharking and extortion.

A campaign against gangs has already snared the head of the judicial bureau and a former longtime deputy head of the police.
