Security concerns have mounted recently

Rio de Janeiro (CNN) The state of Rio de Janeiro will deploy nearly 14,000 security officers -- about a third more than previously planned -- during the coming Olympic and Paralympic Games, Military Police General Commander Edison Duarte said Monday.

Authorities plan to deploy more officers to the Barra da Tijuca area -- the neighborhood where the Olympic Park, Athletes Village and most of the Olympic sporting arenas are located.

The contingent will be part of the 85,000 security officers that have been deployed to the city. In addition to Rio's state police, members of the Brazilian Armed Forces, navy and out of state police will be on patrol throughout the city.

Duarte also announced more than 3,000 vehicles would be used for policing during the Games, as well as three blimps spread throughout the city that will transmit high resolution images in real time.
