One person has been confirmed dead after police fired tear gas at fans outside Gimnasia’s stadium during the match against Boca Juniors in Argentina.
Police, while trying to stop supporters from getting into the already packed stadium, fired rubber bullets.
The game was cancelled after nine minutes, with fans spilling onto the pitch trying to escape the turmoil.
Sergio Berni, Buenos Aires security minister, confirmed there was one death, adding that he “died of cardiac arrest.”
Management of San Martin hospital in La Plata, where Gimnasia is based, also confirmed the death of a 57-year-old man from cardiac arrest as he was transferred from the stadium to the hospital.
From reports, 10,000 fans were outside the 20,000-capacity stadium and could not get in.
Berni said an investigation would be opened, with the possible over-selling of tickets in one area being looked at.
Fans were pressing through fencing to try to get onto the pitch of the Juan Carmelo Zerillo stadium in La Plata.
Referee Hernan Mastrangelo said: “It affected all of us on the field.
“The air became unbreathable. The situation got out of control, and there were no security guarantees.”
The events in Argentina took place in the wake of the recent stadium stampede tragedy in Indonesia, where at least 131 people died.
