Prosecutors in Goias state handling the case told reporters that 255 women had been identified as potential victims whose allegations were being taken into account. Their ages ranged between 9 and 67 at the time they said they were abused.
Police conducted raids on properties linked to Faria and found handguns, gemstones and - hidden behind a false panel in a wardrobe - a suitcase containing the equivalent of US$300,000 in cash.
