A group of some 50 people stormed the Arena Pantanal, in the western city of Cuiaba, as it was being inspected by the Secretary General of Fifa, Jerome Valcke.
They shouted slogans and held banners criticising the huge amounts spent in preparations for the World Cup. http://www.bbc.co.uk/news/world-latin-america-24453842
“Go home!” and “World Cup for whom?” read some of the banners carried by protesters – most of them striking teachers and postal workers.
They have called for more public spending on health and education.
The stadium is expected to cost about £140m ($230m; 500m reais).
Many in Brazil have criticised the decision to build a stadium for more than 40,000 spectators in Mato Grosso state, which does not have a single team in the country’s top football division.
