Brazilian police have arrested five people in an investigation into the causes of the Brumadinho dam disaster.
The dam break on Friday at an iron ore mining complex operated by the minerals firm Vale killed at least 65 people, and a further 279 are missing.
Federal and state prosecutors said 30-day arrest warrants had been issued “aiming to establish criminal responsibility for the rupture of dams at the Córrego de Feijão mine maintained by Vale”.
Arrests were carried out in São Paulo and Belo Horizonte on Tuesday morning, prosecutors said. Searches were carried out at a Vale building in Nova Lima and a subcontracted company in São Paulo that provided services and consultancy to Vale.
