JAKARTA, Indonesia — The Indonesian military is mobilizing over 20,000 personnel to the capital, Jakarta, as a major investigation into an illegal wiretapping operation targeting the presidency unfolds. The scandal has already resulted in the detention of three high-ranking police generals.
The situation has escalated following statements from the presidential palace, which suggested that the surveillance of President Prabowo Subianto could be classified as conduct “leading toward treason.” Officials noted that unauthorized access to a head of state’s communications poses a significant threat to national security and the stability of the country’s leadership.
Among the key figures implicated in the scandal is the presidential chief of staff, Gen. Listyo Sigit Prabowo.
Beyond the presidency, allegations suggest that a wide array of targets were subjected to unauthorized surveillance, including cabinet members, politicians, journalists, business leaders, and civil society representatives.
While authorities have not officially linked the troop deployment to the ongoing wiretapping investigation, the movement began on Monday with an initial phase involving 2,100 personnel already stationed in the capital.
According to Vice Adm. Yayan Sofiyan, an assistant for navy operations, troops from outside the capital began arriving Wednesday, bringing the total deployment to 20,980 personnel.
The surge includes marine and navy units, as well as personnel from various training centers and naval bases across Java and Lampung province. Sofiyan added that an additional 13,140 personnel remain on standby for further deployment if necessary.
Sofiyan declined to comment on whether the deployment is a response to heightened political tensions or specific security concerns in Jakarta.
Maj. Gen. Muhammad Nas, spokesperson for the Indonesian armed forces, characterized the movement as a standard procedure to ensure national security and territorial integrity.
“Troop deployments are a normal occurrence,” Nas stated, emphasizing that the military remains prepared to protect the nation and safeguard the integrity of the Republic of Indonesia.
Prasetyo Hadi, the minister of state secretariat, addressed a press conference at the presidential palace on Wednesday, highlighting the gravity of the alleged surveillance.
“When the target is a head of state, the sensitivity of the information involved is immense, and it could potentially be used to jeopardize national interests,” Hadi explained. “Such actions could be viewed as treasonous, as they endanger the interests of the state and its leadership.”
Hadi noted that the government is waiting for the conclusion of the police investigation to determine the specific motives behind the operation.
The investigation gained momentum late Tuesday when police announced the detention of three senior generals suspected of involvement in the illegal interception.
The suspects, identified as Listyo Sigit Prabowo, Ahrie Sonta Nasution, and Eko Hadi Santoso, face allegations including illegal interception of communications, unlawful access to electronic systems, and the unauthorized deletion of electronic data. They were reportedly taken into custody on Sunday.
Police allege the unauthorized wiretapping occurred between 2025 and 2026, during Listyo’s tenure as Indonesia’s police chief, and that the intercepts were ordered without following legal protocols.
Furthermore, the suspects are accused of ordering the deletion of intercepted communication files in late October, allegedly to destroy evidence and cover the tracks of the operation.
Bambang Rukminto, a police analyst at the Institute for Security and Strategic Studies, noted that targeting a sitting president raises far more profound questions than the surveillance of political or business figures.
While surveillance of lower-profile individuals is often used for political leverage or intimidation, Rukminto argued that such an explanation is insufficient when the president is the target.
“If the target is the president, the motive must be scrutinized more deeply. Intimidation of the president is not a plausible explanation on its own,” Rukminto said, urging investigators to determine the ultimate beneficiaries of the stolen information.
“The investigation must establish not only who carried out the surveillance, but also who intended to use the information and which parties stood to gain from it,” he added.
The three suspects face potential charges related to the unlawful interception, recording, or monitoring of nonpublic electronic communications, which carry penalties of up to 10 years in prison.
The suspects have yet to issue a public response to the allegations.
Adrianus Meliala, a criminologist at the University of Indonesia and former commissioner of the National Police Commission, suggested the allegations raise doubts about whether the surveillance served the state or private interests.
“There is a strong suspicion that this wiretapping was conducted to serve the interests of external parties rather than the state or the National Police,” Meliala remarked.
He added that if proven, the case could be interpreted as a form of political activity involving members of the police force.
“No one expected Listyo Sigit Prabowo to be named a suspect,” Meliala said. “However, if these allegations are proven, the case must be viewed through the lens of political maneuvering. Anyone involved in politics must be prepared to face the resulting political consequences.”
