At least 131 people were killed in a football stadium crush in Indonesia, and six people are facing criminal charges.
The maximum sentence for criminal negligent causing death is 5 years.
Police used tear gas on fans who invaded the pitch after a defeat.
Hundreds of tired people fled through the exits.
The police's use of tear gas has caused a lot of anger among the public. The police chief in Malang was fired and nine other officers were suspended.
The head of the home club Arema FC's organizing committee and one of the club's security officers are facing charges.
National police chief Listyo Sigit Prabowo said that two police officers ordered their colleagues to use tear gas. He said that the third knew that the use of tear gas at matches was against the rules of the sport's governing body.
Police units and soldiers were at the stadium that night, according to authorities.
Videos from the incident, which took place on Saturday night in East Java, showed Arema FC fans running on to the pitch after the final whistle, while police fired tear gas at them.
As supporters fled the gas, they were trampled on and killed in a crush. The victims were children between three and 17 years old.
Fans were shown climbing over the fence to escape. There were videos that showed dead bodies on the floor.
Police forces brutally kicking people and hitting people as they ran around the pitch. The incident is unacceptable, according to a policing expert.
Police said the club's officials didn't comply with safety requirements, allowing in a large crowd. The exits were too narrow for people to exit.
The stadium disaster is one of the worst of all time. There were 97 deaths in a crush at the stadium in 1989. They were at the FA Cup semi- final.
