The Joao Havelange Stadium was closed indefinitely Tuesday because of its roof's structural problems, NBC News said.
The stadium in Rio de Janeiro, built in 2007, was discovered to have structural problems. Rio's mayor, Eduardo Paes, said that it could present a risk for spectators of the Olympics in 2016, BBC News said. The stadium has been closed until there are more details available. Paes said the situation wasn't acceptable, and those responsible will be held accountable.
