BRASILIA (Reuters) - Brazil’s Superior Court of Justice (STJ) has freed five Vale SA and Tuv Sud employees that had been arrested after the burst of a dam in Brumadinho that killed more than 100 people and left more than 200 others unaccounted for.

The ruling overturned a lower court decision and set free executives Andre Yassuda, Makoto Namba, Rodrigo Artur Gomes de Melo, Ricardo de Oliveira and Cesar Augusto Paulino Grandchamp, stating that there was no reason for them to be held, the STJ press office said.
