Earlier 2012, a group of unknown individuals with their faces covered invaded the most popular Avenue in the city of São Paulo, SP, Brazil. The Avenida Paulista, (Paulista Avenue).The Movement, if that's what it is, generated questions, panic, and a buzz surrounding the group whose purpose was completely unrevealed.
Witnesses said they made a few appearances in different places of the city (São Paulo), and then started to spread around the world. And also that the activity appeared to be pretty suspect, causing an impact to the local population.
If you Google “Oyster Movement”, you are surely going to intrigue yourself with this weird, still preoccupying event. You may find this YouTube video particularly scary: http://www.youtube.com/
Authorities around the world have slightly checked and said that it's probably a cultural manifest. But assured they are alert for any threats that may surge. So the question remains the same.
What is this movement? What is the Oyster group? Who are they and what they want?
