An investigation has been launched following incidents of illness during Sebestyén Balázs's DJ show, with toxicologists and medical experts involved. Attendees reported symptoms suggesting possible drugging, leading to a police inquiry into drug possession. Urine samples were collected significantly after the incidents, which may affect the results. Experts suspect GHB, known for causing rapid disorientation and memory loss, was involved. However, proving its presence is challenging due to its quick elimination from the body. Emergency services were not equipped for immediate testing, complicating the investigation further.
