Six Jiu-Jitsu Instructors Arrested for Sexual Crimes in Amazonas Over Two Years
In less than two years, six jiu-jitsu instructors have been arrested in Amazonas, Brazil, on suspicion of committing sexual crimes against their students. The cases, which gained national attention, involve victims including children, adolescents, and young athletes. The most recent arrest occurred on Monday, July 20th, involving a 33-year-old instructor in Manaus's Nova Esperança neighborhood. He allegedly committed the abuse in late 2025, approaching a teenage girl when she was alone at home under the guise of discussing her father's work.
Arrests spanned from November 2024 to July 2026. The first case in November 2024 involved Alcenor Alves Soeiro, 56, arrested in Balneário Camboriú, Santa Catarina, after three students reported him. He was later convicted and sentenced to 178 years and 5 months for sexual abuse. In June 2025, an instructor in Humaitá, Amazonas, was arrested for allegedly raping at least five boys aged 7 to 11 within his home-based academy.
In April 2026, Melqui Galvão, a jiu-jitsu coach and civil police officer, was arrested in São Paulo following accusations of abuse against at least three victims in Manaus, including a 17-year-old. Investigations began after a former student reported non-consensual sexual acts during an international competition. On June 1st of the current year, a 59-year-old instructor was arrested in Manaus for allegedly producing, storing, and sharing child sexual exploitation material involving a 14-year-old. Finally, on June 6th, Carlos Vieira Holanda was arrested after being a fugitive for over a month, investigated for offenses including statutory rape and sexual exploitation of at least seven teenage female students. He allegedly promised benefits like uniforms and competition fees, taking students to hotels for abuse and facilitating their exploitation for financial gain.
The pattern of arrests highlights critical vulnerabilities within martial arts instruction environments, particularly concerning power dynamics between instructors and young, impressionable students. These incidents underscore the importance of robust background checks, transparent reporting mechanisms, and consistent oversight for individuals entrusted with the physical and emotional development of minors. Future considerations should include mandatory safeguarding training for all coaches and the establishment of independent bodies to investigate allegations, ensuring accountability and fostering a safer environment for athletic participation. The systemic issues revealed suggest a need for enhanced regulatory frameworks across sports organizations to prevent similar occurrences and protect vulnerable populations.
