Over 100 Puerto Rican police officers and prison guards have been arrested in a dawn swoop by American FBI agents.
It has been described as the Investigation Bureau’s biggest ever police corruption probe and it took place in the US Caribbean territory.
Those detained were charged with drug trafficking and weapons smuggling offences.
Speaking in Washington, US Attorney General, Eric Holder applauded the crackdown on corruption.
“You had an investigation that lasted over two years; you moved 750 FBI agents from various parts of this country to Puerto Rico, and there was not one leak, there was not one disclosure during the course of that investigation,” said Holder.
The cases date back to 2008 and allegedly include undercover drug purchases as well as police officers
providing security services for drug transactions and receiving hundreds to thousands of dollars in return.
If convicted, the defendants could face sentences of 10 years to life in prison.
