Brasilia / New Delhi, July 20 (TIWN): The Brazilian government has announced increased security at the Rio International Airport, all across Rio city ahead of the upcoming Olympic Games slated to begin on August 5.

Indian olympic delegation including Tripura's golden girl Dipa Karmakar will be under tight security as massive mob violence, murders rampant across Rio City.

Some 1,200 security personnel have already started training and will be stationed in the airport beginning next week. Simulations of situations with bombs were held earlier on Tuesday, with the participation of police, armed forces, trained dogs and even robots, Xinhua news agency reported.

Security from 100 countries and regions will help enhance the security of the Olympic and Paralympic Games. 

Spanish Olympic Committee (COE) has taken the unusual step of hiring its own private security firm for next month's Olympic Games, according to media reports.

The Marca newspaper on Sunday said the COE had contracted Madrid-based Prosegur to shadow the country's athletes and officials during their stay in Rio, reports Xinhua.

It added that it was the first time the COE had hired a private company for an Olympic Games.
Prosegur will be responsible for monitoring the movement of all members of the Spanish delegation and keeping watch at four official team hotels, according to the report.

In May three member's of Spain's Olympic sailing squad were robbed at gunpoint while walking to breakfast in the hilltop Rio neighbourhood of Santa Teresa.
Some 88,000 soldiers and police will be deployed during the August 5 to 21 Rio Olympics, more than double the number used at the London 2012 Games. 

According to regional security coordinator Cristiano Sampaio, there is a special task force to deal with terrorism threats, with the participation of officers from several countries and regions.
"There is a specific anti-terrorism center, with the participation of agents from six countries (and regions), which recently suffered with terrorism or face that problem in their realities - US, France, England, Belgium, Paraguay and Argentina," he said.

With the recent terrorist attacks in Europe, security was increased for the Olympic Games, and Brazil's intelligence agency, Abin is working alongside other organisations to deal with the possibility of attacks during the tournament. 

The Olympic Games will start on August 5 and the Paralympic Games start on September 7.
