Mexican media write about several groups of demonstrators at the stadium. An education union that advocates higher wages and pension reforms had announced that it would move to the stadium in Mexico City. But there are also mothers of missing people, for example.
According to the newspaper La Jornada masked people then sought confrontation with the police. News site Latinus speaks of riots that started almost immediately after the first whistle.
La Jornada also has photos of a person who allegedly tried to throw a Molotov cocktail at police. That went wrong, after which his own hair caught fire.
