Nabire police officers allegedly arbitrarily arrested Ken Boga at Karang Market, Nabire, 3 September 2024, in the afternoon. Boga was arrested because he was allegedly involved in the persecution that caused the death of a security guard named Supriyono at the Security Post of CV Kurnia Jasa Mandiri, Jalan Poros Samabusa, Nabire Regency, 23 August 2024.

Boga's arrest and whereabouts were covered up by the police, making it difficult for family and friends to get a chance to see his condition.

During his detention, Boga claimed to have been abused by a number of police officers. He was forced to confess.

Apart from Boga, the police also arrested two other men, Agustinus Tagi and Yeremias Magai.

According to the family through their lawyer, the three were arrested and tortured to confess. The three of them were in another district more than 60 kilometres away from the murder scene at the time of the incident. In his statement to the Magai family, the police chief claimed to have been pressurised by Supriyono's brother, who is a senior officer at the Cenderawasih Military Command.

On 17 January 2025, the case was tried at the Nabire District Court. On 13 June 2025, the panel of judges found Ken Boga guilty and sentenced him to nine years in prison, one year higher than the prosecutor's recommendation. Ken appealed the verdict, and on 29 August 2025, the appeals court decided to reduce the defendant's sentence to four years in prison. In response, the prosecutor appealed to the Supreme Court. At the end of October, the Supreme Court judges decided to reject the appeal.
