This Brazilian prison gang arose in the country's notoriously brutal penitentiaries 30 years ago but now controls a billion-dollar drug trade supplying much of Europe's cocaine:
-It has been considered a jailhouse fraternity for much of its existence, which recruited incarcerated 'brothers' by offering them protection within Brazil's violent, overcrowded prisons.
-Created in August 1993, it grew into Brazil's most feared criminal faction, conquering drug markets, smuggling routes, shantytowns and prisons across Brazil, including in far-flung corners of the Amazon.
-It also became a major player in other South American countries such as neighbouring Paraguay where the group has been blamed for multimillion-dollar armed robberies and bombings, and targeted assassinations.
-But over the past 5 years, investigators say the gang, which the US now calls one of the most powerful organised crime groups - has morphed into an even more formidable force after forging lucrative alliances with partners ranging from Bolivian cocaine producers to Italian Mafiosi.
-Today, the group boasts 10s of thousands of members and has a growing portfolio of interests, including illegal goldmines in the Amazon.
-It controls one of South America's most important trafficking routes - linking Bolivia and Brazil to Europe and Africa - and is partly responsible for a tsunami of cocaine that has brought car bombings, assassinations and gunfights to parts of Europe.
-"If someone is using cocaine in France, England or Spain there's a very good chance it got there through the hands of the PCC", said Lincoln Gakiya, a prosecutor from São Paulo.
-São Paulo's organised crime taskforce, Gaeco, who estimates the group now makes $1 billion a year - almost entirely from international trafficking.
