BRUMADINHO, Brazil — The Brazilian police on Tuesday arrested five people, including three employees of the giant mining company Vale, as part of an investigation into a dam rupture that left at least 65 dead and 279 missing.
The dam, filled with mining waste and sludge, burst on Friday afternoon, sending a tidal wave of mud crashing down on homes in the town of Brumadinho in southeastern Brazil. The torrent also struck Vale administrative buildings, including the company cafeteria.
The other two people arrested were engineers working for the Brazilian subsidiary of the German industrial testing company TÜV Süd, the company said in a statement. The subsidiary carried out an inspection of the dam’s safety in September, it said, though it refused to comment further, citing the continuing investigation.
Brazilian federal and state prosecutors said in a news release that the five arrests, as well as seven search warrants that were executed, were “aimed at investigating criminal responsibility for the rupture.” The arrests were focused on individuals who had been involved in the most recent safety and environmental survey, which concluded that the dam was “stable.”
The Vale employees arrested were directly involved in and responsible for the mining enterprise and its licensing, according to the statement. The other two people arrested had “attested to the stability of the dam on a recent date.”
In a statement posted to Twitter, Vale said that it was fully cooperating with the authorities: “Vale will continue to support the investigations in order to determine the facts, in addition to the unconditional support to the families #Brumadinho.”
Vale faces mounting anger and public pressure as the death toll rises and rescue workers acknowledge that efforts to dig through the sludge are focused more on finding bodies. The company also jointly owned another dam 75 miles away, near the town of Mariana, that burst three years ago, killing 19 people and unleashing one of the worst environmental disasters in Brazilian history.
