Indonesian Ulema Council shooting

The attack involved a lone male attacker that attempted to meet Kyai Haji Miftachul Achyar, one of the leaders of MUI. He approached the reception area and asked to meet Achyar. Suddenly, the attacker drew an airgun and fired several shots. The shots hit glass doors.[6] It was later revealed that three shots were randomly fired by the attacker.[7] During the panic, one employee was hit by a ricocheted bullet, and another one was injured due to hitting broken glass during their escape.[3] At the time of the attack, MUI leadership was holding a special meeting.[8]

After firing, the attacker attempted to flee the scene, but was pursued by MUI guards and employees. Suddenly, the attacker fainted and collapsed, and was subsequently neutralized by the guards. The attacker was then brought to Menteng police station, and later transferred to Menteng Health Center. Police announced that the attacker died there.[6] Police emphasized that the attacker died at the Health Center, and that they did not cause the attacker's death.[9][10]

The perpetrator was later identified as a man named Mustofa or Mustopa NR, a 60-year-old resident of Sukajaya Village, Pesawaran Regency, Lampung. He had claimed prophethood.[11][12] Police later released a statement that the perpetrator had been convicted in 2016 for vandalism by the Lampung Regional Representative Council office and had already served his sentence.[13][14][15] Police revealed that during this period, he often claimed that he was a "vice of Muhammad".[16] The attacker's family had acknowledged the identity of the attacker.[17] The Sukajaya Village Head, Tarmizi, acknowledged that the attacker is one of his villagers, and said that the attacker was a cocoa farmer along with his wife.[11] He also said that the attacker did not join any religious group to his knowledge.[11] However, the neighboring locals reported that the attacker often claimed to his neighbors that he was a prophet. The locals, however, pay little attention and already get to use with his claims. Despite his beliefs and claims, locals were not feeling irritated or annoyed due to his kindness and he loved to give gifts.[18]

Anwar Abbas, Vice General Secretary of MUI, revealed that the attacker had previously attempted to meet Achyar and tried to discuss his teaching with him.[19][20] He revealed that the attacker also sent several inflammatory and threatening letters to MUI.[21] Cholil Nafis, one of the leaders of MUI, also revealed that in the last two letters, the attacker had expressed his frustration caused by neglection of his teaching and later threatened to attack MUI with guns and knives.[22] MUI later revealed that the attacker had sent letters to MUI six times.[23] However, all six letters were ignored as the contents were considered jumbled, incoherent, unspecified, and without focus.[24] During the attack, another MUI official Ikhsan Abdullah stated that the attacker claimed to be God himself.[25]

Police discovered several letters written by the perpetrator in his bag. The police confiscated the letters and his other belongings for the investigation.[26] One of the letters asked the MUI to acknowledge his prophethood, and the perpetrator claimed that he is a prophet sent by Allah to unify Indonesian Muslims. The perpetrator believed and claimed that by accepting him as the prophet, MUI would have facilitated a greater good.[27] Another discovered letter directed his frustration to the Chief of Metro Jaya Police for not helping him to meet the MUI officials to fulfill his so-called prophethood mission, and asked the Chief to arrest or execute him as the attacker considered him "useless" for not fulfilling his mission.[28] A bank account book under the name of the attacker was also discovered.[29] Various heart medications and asthma medications were also discovered in the perpetrator's bag, which fit his family's account of his illnesses and health records.[30] However, the police waited for the autopsy results from the coroner.[30] On 5 May 2023, the coroner reported that the perpetrator suffered massive heart attack after the attack, which contributed to his death.[31]

Police also investigated the attacker's potential connection to a terrorist organization.[32] Later investigation revealed no detectable links to any terrorist organization.[33] The investigation revealed that the attacker was motivated solely by his desire for the MUI to acknowledge his position as a "vice prophet" and "representative of God", based on his skewed interpretation of hadiths on apocalypse and afterlife salvation. Police also uncovered some planning documents authored by the attacker dated back to 2018 revealing a desire to attack MUI and several other government officials if his demands were not fulfilled.[34]

On 9 May 2023, three people arrested by the Police for aiding the perpetrator by providing weapon for the perpetrator. Police revealed that the perpetrator was also scammed by the weapon's provider, as they provide the perpetrator with the modified air gun instead of the real gun he requested.[35] The main weapon provider was a ranger of Lampung Province Department of Forestry. He was illegally sold unregistered weapons prior the incident. Eventually, as the facts related to the incident revealed, the weapon provider was burdened by the guilt and surrendered himself.[36]
