On 1 October 2022, a fatal crowd crush occurred following an association football match at Kanjuruhan Stadium in Malang Regency, East Java, Indonesia. Following a loss by home side Arema to their rivals Persebaya Surabaya, around 3,000 Arema supporters invaded the pitch. Police said that the rioting supporters attacked the players and the team officials. The police attempted to protect the players and stop the riot, but the crowds clashed with security forces. In response, riot police units deployed tear gas, which triggered a stampede of people in the stadium trying to escape the gas. A crush formed at one exit, resulting in fans being asphyxiated.
