Querétaro–Atlas riot

On 5 March 2022, during a Liga MX football match between Querétaro F.C. and Atlas F.C., a riot broke out between fans attending the match at Estadio Corregidora in Mexico. Videos posted on social media showed groups of men beating, kicking, whipping, dragging and stripping victims.

According to the Querétaro state's civil protection agency initial statement, at least 22 men were injured. This number was updated to 26 the following morning. Claims of death among supporters attacked during the riot is disputed. While no deaths were officially confirmed, some deaths were reported by Atlas fans. David Medrano Félix, a journalist from TV Azteca, originally announced that there had been 17 deaths, but later retracted his report.

Background
The conflicts between Querétaro F.C. and Atlas F.C. date back to 2007, when Atlas relegated Querétaro from the Primera División de México league at home (Estadio Jalisco) during the Clausura 2007 tournament. During that game, there were more Querétaro fans than Atlas fans. Three years later, when Querétaro were back in the Primera División league, and during the 2009–10 Mexican Primera División season, Atlas fans outnumbered Querétaro fans at home (Estadio Corregidora) and clashes were reported in the stands. Since then, conflicts between the barras (groups of conflictive fans) of both teams have existed and the matches between the teams have been seen as potentially problematic.

Riots
Querétaro was playing a match against the Liga MX Apertura 2021 champion, Atlas with kick-off time at 17:00 CST (UTC−6). Julio César Furch scored a goal for Atlas at the 28th minute, which stood for the remainder of the match. Confrontation between the supporters of both clubs began at the 57th minute; play stopped at the 63rd minute as fans sprinted onto the pitch to avoid the fighting from the supporters. At the 102nd minute, the referees suspended the match.
