This is just one of many cases of human (and especially women) rights violation that happen in Brazil.
In some areas they have what can be considered an "evolution" of the colonial system mixed with the behaviour that became common during the military
dictatorship, making the rich, the powerful and the authorities behave as if they owned the land and the people.
In this case the police says that the girl, accused of theft, remained in custody because she could not provide her ID to prove her age, and as the
police station does not have cells for women they put her in the same cell as the men (in Brazil is common to have some 10 or 20 people in the same
cell).
The girl was arrested in the act of committing the theft, and at the time said she was 20 years old, according to a responsible from the police, and
the girl was submitted to medical tests to see what her real age is.
One of the reasons for the existence of doubts about the age of the girl is the fact that her natural father presented a birth certificate that shows
her as being 20 years old while her stepfather showed a certificate where she has only 15.
According to the same police agent (I do not know how to translate that post, "delegado") her stepfather has a fake certificate to assume her
paternity when he went to live with her mother.
The girl has been arrested in other occasions.
But the suspicions against the police officers involved are many, fuelled by the fact that the police did not let her out when members of the office
responsible for minors went there with the birth certificate showing her as a 15 years old and told them to get back on the following day. When they
returned she wasn't there, and the police said that she had run away. She says that the police left her on the port and told her to get aboard a boat
and go to a far away place.
Three of the agents involved were suspended, the superintendent for the region, one "delegado" and one
police-woman, also a "delegada",
that arrested the girl and that sent her to the cell. The prison agents were also suspended, and all were suspended to avoid interference with the
investigations.
One of the prisoners said the they were against the idea of putting her in the same cell, saying that it was wrong and that she was a minor, but he
said that the police put her in the cell and even hit her.
The prisoners were after transfered to a different jail.
The governor of the state of Pará said that there is a suspicion that the girl might have been put in the cell to be sexually exploited by the
prisoners.
