One person died, 41 people were injured and 78 arrested as the second-leg of Argentina's promotion/relegation play-off between Nueva Chicago and Tigre was marred by violence.

Leading 2-1 in the game and 3-1 on aggregate, Tigre were on course to be promoted to Argentina's top flight when they were awarded an injury-time penalty.

However, the visitors were prevented from taking the spot kick that would have confirmed their ascension as Nueva Chicago's fans invaded the pitch.

The situation soon descended into chaos as a fight that began inside the Nueva Chicago Stadium spilled onto the streets, causing a large traffic jam on General Paz Avenue.

The 41-year-old man, who was not named, died after being hit on the head by a stone thrown by a supporter according to reports.

Director of emergency ambulance service SAME Doctor Alberto Crescenti added the man 'was admitted to Santojanni hospital in a very critical condition and died very soon afterwards.'

Chief of Police Claudio Marcelo Stabile, who led the security operation, revealed 78 fans had been detained and the Nueva Chicago stadium was shut down immediately. Ten policemen were also hurt.
