At least one person was killed and several others were injured on Friday during an event held at the Alejandro Villanueva Stadium in Lima, the home ground of Alianza Lima, the club said in a statement.
Local media reported that approximately 60 people sustained injuries in what was described as a "flag‑waving event" at the stadium, commonly referred to as Matute. The casualties occurred ahead of a derby match between Alianza Lima and Universitario scheduled for the following day.
In its announcement the club expressed condolences to those affected and stated it was offering solidarity to the victims. The club also said it was "fully and transparently collaborating with the competent authorities" and pledged "total transparency" in assisting efforts to establish the facts surrounding the incident.
Officials have not yet determined the cause of the incident. The club and emergency services have notably ruled out any structural failure at the stadium as a factor. Marco Pajuelo, a fire official, told Canal N that an initial inspection indicated no structural elements had been affected and that investigators had not found evidence of anyone having fallen into a pit. He added, "There hasn’t been any debris."
Despite the fatalities and injuries, the Peruvian Professional Soccer League announced that Saturday’s derby would proceed as planned. The league said it will keep working closely with clubs and authorities to promote safety both inside and outside stadiums.
The sequence of events, the exact cause of the injuries and the full extent of casualties remain matters under investigation. Authorities and club representatives are engaged in inquiries and coordination, and further details are expected as those inquiries continue.
Summary: A flag‑waving event at Alejandro Villanueva Stadium resulted in at least one death and numerous injuries before a scheduled derby between Alianza Lima and Universitario. The club and emergency officials say there was no structural failure and are cooperating with authorities; the league confirmed the match will go ahead.
