Public prosecutors have moved to halt construction at the World Cup stadium where a worker fell 115 feet to his death while working on the roofing structure in Manaus, according to the Associated Press.
Prosecutors want the "immediate" interruption of work in all areas where labourers need to be high above the ground.
They said work should only restart after constructors show that all safety measures are in place at the Arena da Amazonia, the stadium hosting four World Cup matches next June, including England v Italy and United States v Portugal.
