Some 20,000 thousand police offers and military troops are to be deployed in Rio De Janeiro to bolster security for the fast-approaching World Cup.
The decision to beef up the security was prompted by the recent protests that have swept through the country.
On top of the additional personnel, forces will have extra patrol cars, helicopters and boats at their disposal.
Anderson Bichara, the central command coordinator for the Rio De Janeiro security delegation, said: “The protests are a part of democracy, of expressing ideas and trying to change the current situation. But we have noticed that protests can also become violent, there may be some excesses.”
Brazil was hit by some of the country’s biggest ever protests last year when a rise in public transport costs was met by mass discontent and often violent clashes with police, who were later criticised for their brutality.
The additional security forces in Rio will start patrolling city streets on Friday.
Rio is to host seven matches, including the final on July 13.
