The Chronicle had access to the video of the testimony of an inmate of the Dr. Osvaldo Florentino Leite Ferreira penitentiary, known as Ferrugem, in Sinop (MT), in which he reports alleged plans of criminal police officers to attack the authorities who coordinated an inspection and exposed the practice of torture against inmates of the unit.
During the hearing, the prisoner — named as one of the leaders of the Comando Vermelho (CV) in the region — said that agents, allegedly at the request of prison management, had asked him to try to attack a judge and a prosecutor during a hearing. According to the report, the criminal officers intentionally left their handcuffs loose to facilitate the action.

“It’s not worth asking for a harsh sentence and defending amnesty,” says PF director
In exchange for this attack, the inmate claims that he would receive, within six months, authorization to leave the prison and work.
He cites Adalberto Dias de Oliveira, director of the penitentiary, and deputy director Antônio Carlos Negreiros dos Santos as responsible for ordering prison officers to threaten them.
However, the man revealed the plan during his testimony and showed his loose handcuffs to authorities. Given the complaint, the hearing officials searched for the judicial police officers who should have provided security for the corridor, but none of them were located.
“He told me to attack the honorable people he had at the table. For me to attack and it burns the image of people who come here and see us as aggressors and then he was going to give me an opportunity in six months, if I went to church he would take me to work (sic).”
According to the guard, the absence of agents near the courtroom would have occurred in an orchestrated manner, precisely to allow a possible attack against the authorities.
However, after revealing his plan, he claims to have received death threats. “Two officers mentioned Negreiros’ name and he also threatened me. He said he would find a way to disappear with me anyway (sic),” he said.
The inmate ends his statement by requesting his urgent transfer to another prison. “I don’t even eat, I’m afraid they’ll poison me here, I’m not going to eat (sic),” he said.
The State Secretariat for Justice (Sejus) indicated that it received, on December 12, the inspection report carried out by the Mato Grosso Justice Court (TJMT).
The ministry emphasized that during the year 2025, no official complaints have been filed with any supervisory body regarding alleged cases of torture in the aforementioned penitentiary.

Signs of torture
As reported in this Tuesday’s column (12/16), the General Inspectorate of Justice carried out, between October 29 and 30 of this year, an inspection of the prison.
The report, prepared by members of the Control and Inspection Group of the Prison and Socio-Educational System (GMF), of the Court of Justice of Mato Grosso (TJMT), describes serious situations of human rights violations.
“The guards are forced to sit, shirtless and without flip-flops, with their legs bent and their hands behind their necks – sometimes just in their underwear or completely naked – while the criminal police officers enter the neighborhoods, under insults, humiliation and violence,” states an extract from the report.
The videos
In one of the recordings, a criminal officer uses pepper spray as a form of punishment. The officer rubs the substance on the inmate’s face and, at another point, uses his hands to spread it directly into the inmate’s eyes.
Rubber bullets and dogs were also reportedly used as instruments of torture. In some images, the animals are positioned in front of the inmates, barking aggressively, while the inmates try to protect themselves with their arms.
One of the guards interviewed by professionals had a deep bite on his buttocks. Another detainee had bite marks on one of his hands, signs consistent with the use of dogs during the reported acts.
The interviews
During the inspection, teams interviewed 126 detainees. Among them, 48 had scars or recent injuries caused by rubber bullets.
Inspectors also located, inside the cells, rubber ammunition caps and a pre-detonated grenade, allegedly having a morale effect, reinforcing allegations of excessive use of force within the prison unit.
The document concludes that there is, in the prison, the consolidation of a parallel power aimed at the exercise of “its own justice”, in direct opposition to the Court of Justice, the Surveillance and Inspection Group (GMF) and other control bodies of the prison system.
