Madrid Arena tragedy
On 1 November 2012, a Halloween party featuring Steve Aoki resulted in five girls being crushed to death and a further 29 people were injured. There were 16,600 people crowded into the hall, authorized for 10,600.

A few days later it was announced that the Madrid Arena was not going to host the Handball World Championship as expected, due to its safety problems. In 2015 the Spanish writer Saúl Cepeda Lezcano, who worked for the main parties blamed for the tragedy, published the novel Aforo Completo (Full House). The book uncovers many illegal activities in nightlife and clubbing activities that had led to a similar disaster.
