On 1 October 2022, a fatal crowd crush occurred at Kanjuruhan Stadium in Malang Regency, East Java, Indonesia, following a Liga 1 football match between home side Arema and rival Persebaya Surabaya. Persebaya won 3-2, its first-ever away win over Arema, and roughly 3,000 Arema supporters, known as Aremania, invaded the pitch afterward; police said the invading supporters attacked players and team officials. Police and the Indonesian Army moved to disperse the crowd, and officers began firing tear gas into the stands and onto the pitch, affecting rioting supporters and other spectators alike and triggering a mass rush for the exits. Police said 11 rounds of tear gas were fired, while other contemporaneous reporting cited in the source put the figure at 40 or more within ten minutes. Most gates were locked except gate 14, and a crush formed at gates 13 and 14, asphyxiating many of those trying to flee.
By 24 October 2022, the confirmed death toll reached 135, with 583 others injured, making the event the second-deadliest stadium disaster in the history of association football, after the 1964 Estadio Nacional disaster in Peru. Death-toll reporting varied in the disaster's immediate aftermath: the Indonesian National Police and the Malang Regency Office of Health each reported 131 deaths, while a crisis center established by the Malang Regency government reported 133; Aremania disputed the official figures, alleging that more than 200 people may have died and that some bodies were returned directly to families rather than counted at hospitals. Reports on child victims also varied, citing either 39 children aged 3 to 17 or 38 victims under 17 among the dead; the youngest victim was 3 years old and the oldest was 45.
Indonesia's national police chief, Listyo Sigit Prabowo, announced on 6 October 2022 that six people had been placed under suspicion: the director of the match's organizer, two Arema officials, and three police officers, over negligence and the use of tear gas. A first trial opened in Surabaya on 16 January 2023. Of the six people prosecuted, three received prison sentences and one was released for insufficient evidence, while two police officers, Wahyu Setyo Pranoto and Bambang Sidik Achmadi, were initially acquitted after the presiding judge stated that 'the wind is guilty for the fatalities'. On 23 August 2023, Indonesia's Supreme Court annulled those acquittals, sentencing Pranoto to two years and six months in prison and Achmadi to two years.
An independent forensic team exhumed and re-autopsied two victims, aged 13 and 16, in November 2022 at the request of their father, Devi Athok, who alleged police intimidation and disputed the official cause of death; the team concluded the deaths were caused by bleeding and rib and chest fractures, with no tear gas residue found in the lungs, though the bodies had decomposed before sampling. On 31 December 2024, the Surabaya District Court ordered restitution of IDR 1.02 billion to 71 petitioners, well below the IDR 17.2 billion requested, and the petitioners said they intended to appeal. Kanjuruhan Stadium was subsequently demolished and rebuilt, with reconstruction completed in January 2025 at a cost of Rp 350 billion. Contemporaneous coverage of the disaster was also published by the Associated Press and BBC News.
