This week, federal prosecutors arrested 22 officers, including the third-in-command of the city's military police, on charges of running an extortion racket involving shopkeepers and bus and taxi companies.

The commission believes the police were involved in an extortion racket in which they arrested individuals and then demanded money from relatives to secure their release.

His tales of extortion rackets led to five arrests.

As well as extortion rackets, the groups also worked in car insurance and theft.

Through civil suits and new regulations, the city expelled mob employees and vendors and ended the extortion rackets against honest seafood vendors.
