The velodrome built for last year

The velodrome built for last year’s Rio de Janeiro Olympics suffered minor fire damage Sunday when it was struck by a small, hand-made hot-air balloon.
Police initially kept photographers and reporters from getting close to the building in the Olympic Park, but charred areas could be seen on the roof of the structure.
The Brazilian sports ministry confirmed the incident with no injuries reported. In a statement it said the damage was being evaluated.
Despite being illegal, the release of the hand-made balloons is common in Brazil. The balloons often cause fires when they land.
The incident took place just a few days short of the one-year anniversary of the Rio Games, which opened on Aug. 5.
The velodrome cost about $45 million and, like a half-dozen other sports arenas in the Olympic Park, is struggling to find a use. Many of the arenas are boarded up, and the park in suburban Barra da Tijuca is largely vacant with few amenities for visitors.
Brazil spent about $13 billion in public and private money to hold last year’s Olympics, with some reports suggesting the overall cost is closer to $20 billion.
The costs are a flashpoint because Brazil is going through its deepest recession in a generation.
The state of Rio de Janeiro has been late paying teachers, police and pensions, and the military has been arriving in Rio over the last few days to try to control the city’s soaring violence
