Scary scenes in Torreón last night as the Primera match between Santos and Morelia was abandoned due to a gunfight between drug cartels and Mexican police. It happened around the 40 minute mark of a match that was 0-0 when the sounds of gunfire could be heard. Players, referees, and technical staff ran for the tunnels while spectators crawled into the spaces in front of the seats. What had happened was that a criminal group traveling in a three car caravan failed to stop at a police checkpoint near the stadium and the occupants engaged the police in a confrontation that left a soldier injured. One of the abandoned cars contained a cache of small arms.
You can find photos and videos of the incident at Medio Tiempo and at Argentina's sports daily Olé.
Drug cartel violence has become a lamentable feature of Mexican life in the last five years, but I have never heard of such violence interrupting a Mexican football league match, and according to the reporter at Medio Tiempo it has never happened before.
