The National Police’s ethics commission has dismissed a Mobile Brigade (Brimob) officer over the death of an online motorcycle taxi driver who was fatally struck by an armored vehicle during violent protests in Central Jakarta late last month.

Commissioner Cosmas Kaju Gae, Battalion commander of Brimob’s 4th Regiment, was dishonorably discharged on Wednesday, September 3, 2025, following a hearing by the National Police Code of Ethics Commission (KKEP).

The decision came after investigations found serious misconduct in connection with the August 28, 2025 incident that killed the motorcycle taxi driver Affan Kurniawan.

“The behavior of the offender was deemed disgraceful. He had served six days of special detention from August29 to September 3. The panel has ruled for dishonorable discharge from the police force,” KKEP presiding officer, Senior Commisioner Heri Setiawan, said.

Six other Brimob personnel are also facing disciplinary proceedings, while Chief Brigadier Rohmat, the driver of the armored personnel carrier involved, is set to stand trial on Thursday, September 4, 2025. Five others face hearings for medium-level violations in the coming days.

National Police’s Internal Affairs Division (Propam) has earlier confirmed that the case could carry criminal charges. “From our review, the serious violation contains elements of a crime that resulted in death,” Propam inspector Brigadier General Agus Wijayanto said on Monday, September 1, 2025, adding that the case review included oversight from the National Police Commission (Kompolnas) and the National Commission on Human Rights (Komnas HAM).

During Wednesday’s hearing, Cosmas broke down in tears after being dismissed, insisting he had acted under orders. “I was only carrying out my duties and responsibilities, following instructions to ensure public order and the safety of my men, at great personal risk,” he said.

Affan’s death has intensified public scrutiny of police conduct during the protests, which turned violent in several parts of Jakarta. The incident has raised fresh concerns over crowd control practices and accountability within the police force.
