Three girls were killed and two were left in critical condition at an EDM Halloween show in Madrid headlined by Steve Aoki, El País reports.
The three victims – Katia Esteban Casielles, Rocío Oña Pineda and Cristina Arce de la Fuente, all of whom were between 18 and 20 – were reportedly crushed during the Thriller Music Park show, where the crowd reached an estimated 10,600 people. María Teresa Alonso Vinateo and Belén Langdon Real are currently receiving treatment in the hospital.
Police are currently investigating whether proper security measures were in place after some witnesses spoke of an "avalanche" of people after a firecracker or flare apparently went off near the entrance of the venue.
According to Deputy Mayor Miguel Ángel Villanueva, 9,650 tickets were sold for 10,600-capacity venue, though it's unclear how big the crowd was at the time of the incident, which happened around 4 a.m. local time. Villanueva added that all the emergency exits were functioning properly and that show organizers, Diviertt, had all the necessary permits.
