Indonesian authorities have arrested four members of the Indonesian National Armed Forces allegedly involved in an acid attack on an activist who had publicly criticised the military’s growing role in civilian life.
On March 13th, 2026, the activist serving as deputy coordinator of the Commission for Missing Persons and Victims of Violence, also known as KontraS, was targeted in an acid attack. It occurred shortly after he had publicly expressed his opposition to the increasing involvement of the Indonesian military in civilian life. According to Dimas Bagus Arya, another coordinator of KontraS, the victim had previously received threats linked to his advocacy work. Human rights observers argue the attack reflects a broader pattern of intimidation against activists who are critical of state institutions and their actions.
Authorities have since arrested four suspects allegedly involved in the attack, and it was recently revealed that they are members of the Indonesian National Armed Forces. The Commander of Military Police stated that the motives remain unclear and are under investigation. He added the possibility of orders originating from higher- ranking officials has not been ruled out. Following the investigation, the suspects should face military trial, raising concerns among observers regarding transparency and accountability.
Human rights organisations argue that this case reveals a troubling trend in Indonesia of increased military intervention to shrink the space where civilians can express their dissent. They also stress that attacks like this one contribute to a climate of fear, undermining freedom of expression and exposing activists to violence and reprisals. Calls for an independent and impartial investigation have intensified, with demands that those responsible are held accountable regardless of their position and that stronger protections be ensured for human rights defenders.
