Three people who allegedly killed at least two women and ate parts of their bodies may have murdered another five people, police in north-eastern Brazil said.
Police spokesman Carlos Leite said investigators suspect the trio murdered four women in the state of Pernambuco and one in neighbouring Paraiba.
He said officers have information indicating that the five "suffered the same fate" as the two women whose remains were discovered last week in the city of Garanhuns.
A man, his wife and his mistress were arrested last week for allegedly killing two women, eating parts of their bodies and using their flesh to make stuffed pastries known as empanadas that they sold to neighbours.
Police hope they will show where the additional bodies are buried.
