MALANG, Indonesia—Dozens of Indonesian police were placed under investigation on Monday over a stampede at a soccer match that killed 125 people, as authorities sought to determine what caused one of the world’s deadliest stadium disasters and who was to blame.
Panicked spectators were crushed on Saturday as they tried to flee the overcrowded stadium in Malang, East Java, after police fired tear gas to disperse fans of Arema FC, who had poured onto the pitch after a 3–2 home defeat to Persebaya Surabaya.
