The national police internal supervisory commission has found that officers used extreme measures during the disbanding of the Papuan People’s Congress in Abepura, Papua on Oct. 19.

The police held code of ethics trials for members believed to be responsible for the incident.

“They have neglected the police code of ethics on duty,” said national police spokesman Insp. Gen. Saud Usman Nasution on Monday.

According to Saud, there were four code of ethics trials.

The first trial involved four Papua police brigade mobile members, including two officers who received written warnings, and two enlisted officers, who were held in a special cell for 14 days.

The second trial was for a former Jayapura Police Chief, who also received a written warning. The third trial included seven Jayapura police officers, who received written warnings, and the fourth trial included five enlisted officers, who received seven days in jail and written warnings.

“Officers, a police chief, persons in charge and members have been on trial and have received their punishments,” Saud said.

They were found not guilty of the deaths of three congress members who were found dead on Oct. 20.

Autopsy results showed that the victims were killed after police had already retreated from the congress site. The police are still looking for the perpetrators.

The victims include Daniel Kadepa, Max Saseyo and Jacob Samansabra.
