AARAU — One person was killed and five people were injured in a shooting at a rave in Aarau, Switzerland. The search for the unknown perpetrator is ongoing.

Aargau Cantonal Police stated that possible motives and the exact circumstances of the crime remain unclear. Police spokeswoman Vanessa Rumpold said several shots were fired within a large group of people. One witness reported bursts of gunfire.

Rave visitors initially mistook the shots for fireworks. The shooting took place right after the event ended. Approximately 3,500 people attended the annual techno party between 3 p.m. on Saturday and 2 a.m. on Sunday.

Police took remaining visitors to a nearby gym. An area around the racing track, the town's swimming pool, and sports field was cordoned off. The Kantonale Katastrophen Einsatzelement (KKE), the regional disaster response unit, was deployed to the scene.

A Swiss Army helicopter surveyed the area in the early hours. Police asked witnesses to share videos or photos of the incident with investigators. Police in Freiburg, Germany, participated in the search efforts for the suspect as part of routine police cooperation between Swiss and German authorities.

DJ Tekibo posted on social media regarding the incident. "What happened at Aarauer rave is absolutely heartbreaking," he wrote. "Techno and raves are supposed to be a place for freedom and safety, never a place where something like this happens."
