Ultra Europe took place this past weekend in Croatia and about 150,000 people from all over the world attended this year’s event. Even though the celebration was one for the books, there were some things that did not go so great. According to police, across the festival’s three days, there were about 305 arrests, a bunch of hospitalizations and one death. One American attendee passed away at Ultra Europe, after he got sick on Saturday and had to be hospitalized. The police announced his death on Monday, but the cause has yet to be revealed.

In terms of the arrests, many of them were for trespassing, breach of peace and possession of drugs.
