In addition to his regular duties, he also served as an aide for the security and protection of the North Kalimantan Regional Police Chief, Inspector General of Police Daniel Adityajaya. “Yes, he was assigned as an aide in Polda Kaltara,” Budi confirmed.

To clarify the cause of death, Brigadier Setyo Herlambang’s body was transported to Tarakan City Hospital for an autopsy.

Currently, the police are conducting a thorough investigation to uncover the cause of his death.

General Listyo also emphasized the use of Scientific Crime Investigation (CSI) in the investigation process.

Multiple mysterious officer deaths under scrutiny

In response to the incident, the Indonesia Police Watch (IPW) has called for the establishment of a special team to investigate the case.

Sugeng Teguh Santoso, Chairman of IPW, said, “The National Police Chief must form a Special Team to investigate this. The aide died at the Regional Police Chief’s official residence. We don’t want a situation like the shooting of Brigadier Yosua to happen again, which tarnished the image of the National Police.”

Sugeng urged an immediate examination to clarify the background of Briptu Herlambang’s death, who was a member of the Brimob unit.

“The disclosure of the death of the Regional Police Chief’s aide is crucial to be transparent and prevent public speculation,” Teguh stated.

IPW also urged the National Police to conduct a comprehensive evaluation of several cases involving the mysterious deaths of their officers since the beginning of 2023.

IPW has recorded at least four such cases.

According to Sugeng, after the case of Brigadier Yosua, who was proven to have been shot by his superior, Ferdy Sambo, the public was also shocked by the death of Chief Police Brigadier (Bripka) AS, a member of the Samosir Resort Police, on 23 January 2023, allegedly due to cyanide poisoning.

Three months later, on 25 March 2023, there was the case of Brigadier Polisi Satu (Briptu) RF, Personal Staff of the Gorontalo Regional Police Chief, who was found dead with a gunshot wound inside a parked official vehicle on Gorontalo Ring Road. RF was suspected to have committed suicide as gunpowder residue was found on his right hand.

Six days later, on 31 March 2023, Brigadier Polisi Kepala (Bripka) DK, a member of the Directorate of Samapta (Ditsamapta) of the Banten Regional Police, was found dead with gunshot wounds in his home in Griya Baladika Asri, Serang City, Banten.

On 23 July 2023, Brigadier Polisi Dua (Bripda) Ignatius Dwi Frisco Sirage, a member of Detachment 88 Anti-Terrorism Special Unit (Densus 88), died at the Polri Cikeas Police Complex in Gunung Putri, Bogor Regency, allegedly killed by his colleagues, Brigadier Polisi Dua (Bripda) IMS and Brigadier Polisi Kepala (Bripka) IG.

From this series of cases, IPW called upon the National Police to investigate and research the psychological issues affecting their personnel. IPW also urged the National Police Chief to examine the leadership practices aimed at guiding subordinates.

“The disclosure of the Regional Police Chief’s aide’s death is crucial to be transparent and prevent public speculation,” Sugeng emphasized.
