On 13 October 2024, around 11:00 am, Yonif 509 Balawara Yudha military members attempted to stop Mr Pianus Sani, 18, and Sepe Bagubau, 15, as the youth drove their motorcycle back home. Fearful of the military members, Mr Pianus Sani did not stop the motorcycle but continued driving. He dropped Sepe Bagubau on the roadside and continued his way home. Shortly after the incident, members of the Yonif Raider 509 TNI Balawara Yudha reportedly detained Sepe Bagau and tortured him inside the military post.
News of the arrest quickly circulated in the community. At 3:15 pm, Father Yance Yogi Pastor Dean went to the Yonif Raider 509 TNI Balawara Yudha Kostrad military post in Mamba along with relatives calling for Sepe Bagubau’s immediate release. Yonif Raider 509 TNI Balawara Yudha Kostrad Task Force stated that they would not release Sepe before Pianus Sani would surrender himself to the military post.
Community members found Mr Sani at his house. He agreed to come to the Yonif Raider 509 TNI Balawara Yudha Kostrad military post to clarify the situation. After surrendering himself, Sepe Bagubau was released. He sustained bruises all over his body as a result of the collective beatings inside the military post. After the relatives had left the post, military members began torturing Mr Pianus Sani inside the post. Mr Sani died inside the military post as a result of the injuries he sustained during the torture. Villagers found the body on the side of the Bilogai Village road on 14 October 2024, at 07.00 am, from where the body was taken to the general hospital. Relatives picked up the body without forensic examination and cremated the body (see photos below, source: independent HRDs.

Following these events, residents, led by church leaders, organised protests demanding accountability for the actions of the TNI and calling for the return of Alex’s body (see videos below, source: independent HRDs). The families of the victims, alongside the affected community, are demanding justice and accountability. They call for an independent investigation into the actions of the TNI Yonif 509, the return of Alex Sondegau’s remains, and the immediate release of all detained civilians. Additionally, they seek a cessation of military operations in Intan Jaya, advocating for the protection of civilians amidst ongoing armed clashes between the TPNPB and security forces in Intan Jaya. Their demands reflect a desperate plea for justice and an end to the cycle of violence.
