A police commander and seven officers are under arrest in connection with the murder of a Brazilian judge.
A court ordered six new arrests late Monday and the Rio de Janeiro state police say the men were detained Tuesday. Two police officers had been arrested earlier.
Murdered Judge Patricia Acioli was known for being tough on rogue police officers who turn to vigilantism and extort money from the population. She was shot to death in front of her house in the city of Niteroi in August.
Among those arrested is Claudio de Oliveira, who headed the police department in the city of Sao Goncalo, where Acioli worked.
