A woman died in the stampede to exit the club.<br/><br/>Pech said the incident began when a person entered the Blue Parrot nightclub armed around 3.00 a.m. on Monday morning, during the closing of the festival. Another person tried to stop the person, sparking a gunfight that drew in security staff.<br/>'<br/>Pech added that 15 people were injured, of whom 10 are still in hospital. Four people were arrested on suspicion of being involved in the incident. The shooting represents a major blow to Mexico's tourism industry, which has been one of the few bright spots in the economy thanks to a weak peso exchange rate.<br/>
