On 1 October 2022, a fatal human crush occurred following an association football match at Kanjuruhan Stadium in Malang Regency, East Java, Indonesia.

[10] On 6 October 2022, Indonesian police chief Police-General Listyo Sigit Prabowo announced that six different individuals and groups had been placed under suspicion: the director of the match organizer PT Liga Indonesia Baru (LIB), the Arema head of security officer, the members of the Arema match organizing committee for negligence, and three police officers for the use of tear gas.

[19][a] Arema and Persebaya Surabaya, longstanding rival clubs at the Super East Java Derby, were scheduled to play a Liga 1 regular season match at Malang's 42,000-capacity Kanjuruhan Stadium on 1 October.

According to a witness, they were chased by the police, who pulled off their shirts and beat them; this triggered other supporters to enter the field area.

They scattered around, looking for their team's players and officials, and demanding their explanation of the defeat "after 23 years of undefeated home matches" against its rival Persebaya.

[32] Security officials and police tried to divert more Aremania away from the pitch, but to no avail, forcing the Indonesian Army (TNI-AD) and Mobile Brigade Corps' Anti Riot Unit (PHH) to be called in to assist with the dispersal of the angry supporters.

[41][42] Aremania disputed the official numbers, alleging that more than 200 people may have perished, as the bodies of some of those who died were immediately returned to their families instead of being transported to hospital.

[49] On 4 October 2022, Widodo announced the provision of additional financial compensation in the amount of Rp 50 million (USD 3495) from the central government to each deceased's next-of-kin.

[52] The Indonesian Football Association (PSSI) apologised for the incident and announced a ban on home matches for Arema for the rest of the season.

[53][54] PSSI also stated that the decision by PT Liga Indonesia Baru, the organiser, to hold the match had been agreed to by other stakeholders of Indonesian football.

[57] Also on 3 October 2022, PSSI announced that the 2023 AFC U-17 Asian Cup qualification group B matches, which was held in Indonesia, would be played behind closed doors starting that night.

Commander of the Indonesian National Armed Forces Andika Perkasa promised that the act would not be considered self-defence, and the soldiers involved would be charged under criminal law.

[67] The National Commission on Human Rights of Indonesia (KOMNAS HAM) announced plans to investigate the incident and the use of tear gas by police.

[68] Although FIFA's rules say that tear gas should not be used inside stadiums, the chief of regional police defended its use, citing the threats posed by the rioters to players and officials.

[71] On 14 October 2022, Narasi, an Indonesian independent news office, released a visual investigation detailing how the disaster unfolded, and highlighting the over-zealous use of tear gas.

Ahmad Hadi Lukita, the director of PT Liga Indonesia Baru, was charged for his negligence of stadium verification.

Abdul Haris, Arema match organising committee chairman, was charged for not fulfilling the obligation of creating a set of safety rules or guidelines for spectators, as well as allowing ticket sales above stadium capacity.

[88] At the time of the fact-finding team announced the final report, BRIN had not yet finished analysis of the tear gas samples and was still assessing the toxicity and performing complete toxin profiling.

According to Mahfud, TGIPF came to the conclusion that the root cause of the panic that resulted in the deaths of hundreds of people was tear gas.

[95] The fact-finding team also found CCTV footage at Kanjuruhan Stadium which was thought to be deleted, indicating a possible cover-up attempt.

[96] On 5 November 2022, an independent team from the Indonesian Forensic Doctors Association performed autopsies on the bodies of two disaster victims after they were postponed.

[108] Video footage circulating on social media depicted these officers, identifiable by their distinctive navy-blue berets, mocking and taunting the prosecutors as they arrived on 14 February 2023 for the ongoing trial at the Kanjuruhan Stadium in Malang.

[109] Despite the fact that independent sources (including Narasi, Antara News, and The Washington Post) reported that a large number of tear gas projectiles were discovered in the stands, a presiding judge in the court case stated that "the wind is guilty for the fatalities" in the disaster.

[110][111] On 23 August 2023, the Indonesian Supreme Court annulled the initial verdicts of the two police officers, named Wahyu Setyo Pranoto and Bambang Sidik Achmadi.

[120] Prior to this, the victims had already received financial assistance in the form of donations from Arema FC, as well as support from the central and regional governments through the KIS program.

According to him, the use of tear gas in stadiums is prohibited by FIFA and is not included in the standard operating procedures for securing football matches.

Sahroni asked the National Police Chief General Listyo Sigit Prabowo to take firm action against the officers responsible for the use of tear gas.

[122][123] On 6 October 2022, Widodo sent a letter to FIFA President Gianni Infantino through Minister of State Owned Enterprises Erick Thohir.

As replacement, the police only authorized the use of hand-to-hand martial arts and defensive tools such as riot shields and batons for securing the sporting events.

The defensive barricades will also be erected in other designated protected areas inside and outside the stadium to ensure the safety of the team supporters, spectators, players, and officials.
