Bripda Mesias Siahaya, Brimob Officer Who Assaulted Madrasah Student to Death, Officially Dismissed — Considering Appeal
Ambon — Maluku Police Chief Inspector General Dadang Hartanto personally led the press conference announcing the results of the National Police Professional Code of Ethics Commission (KKEP) hearing against Maluku Mobile Brigade (Satbrimob) member Bripda Mesias Siahaya.
At the hearing, Bripda Mesias was officially handed the sanction of Dishonourable Discharge (PTDH). Addressing the media, Dadang affirmed that the National Police will not tolerate serious violations, particularly those that undermine public trust.
“The National Police will not tolerate any form of ethics code violations or violent conduct that damages the values of professionalism and public trust. This case has been handled objectively, transparently, and justly,” he said on Tuesday, 24 February 2026.
The PTDH ruling was read out during the KKEP hearing chaired by Commission Chairman Senior Commissioner Indera Gunawan. The panel examined a total of 14 witnesses, comprising 10 who appeared in person and four via video conference, including the victim’s witnesses and police officers from various units.
Based on the trial findings, the panel concluded that the accused officer was proven to have violated obligations to uphold institutional honour and reputation, to comply with legal norms, and to have breached prohibitions against committing acts of violence and improper conduct.
In addition to the ethical sanction of a declaration of reprehensible conduct, the KKEP also imposed an administrative sanction of placement in a special facility for five days, which has already been served. The most severe sanction handed down was dishonourable discharge from the National Police.
Dadang reiterated that this decisive action represents the institution’s commitment to cleansing its ranks of serious violations.
“The outcome of this hearing is a tangible demonstration of the institution’s commitment to upholding internal discipline and ethics, whilst ensuring that every police officer found to have committed violations will be dealt with firmly and without discrimination,” he said.
Nevertheless, Bripda Mesias Siahaya stated he would take time to consider the ruling. This means the individual still retains the right to file an appeal in accordance with the mechanisms and deadlines stipulated in the National Police’s internal regulations.
The Brimob officer had previously been reported as the perpetrator of an assault against a Madrasah Tsanawiyah (MTs) student identified as Arianto Tawakal (14), which resulted in the student’s death near the Uningrat Campus in Tual City, Maluku, on Thursday, 19 February 2026. He was subsequently detained at the Tual Police Detention Centre. Maluku Police have assured the public that the legal process against the rogue officer will proceed without compromise.
