An incident in the Jorge Thiago Aguiar Afonso Penitentiary in Porto Velho, Brazil, involved an inmate being injured by another inmate using a handmade weapon known as a 'xunxo', which is crafted from iron bars within the cell. The attack occurred when the victim approached the cell of another inmate, who launched the weapon through a hole in the cell structure, injuring him in the right eye. Following the incident, prison staff administered first aid before the victim was transported to Hospital João Paulo II for further treatment under police escort.

The police reported that after the attack, the suspect exhibited aggressive behavior and refused to surrender the weapon used in the assault. This raised concerns about the safety and security within the prison environment, prompting a call for additional assistance to handle the threatening situation. The ongoing violence among inmates highlights issues related to prison conditions and the potential for further incidents if not adequately addressed.

Prisons in Brazil, particularly in regions like Porto Velho, often face challenges such as overcrowding, inadequate resources, and violent conflicts between inmates. This incident underlines the urgency for reforms and improved management strategies within the penal system to ensure the safety of both inmates and staff, while also addressing the root causes of violence in correctional facilities.
