Swiss man arrested by police over deadly rave shooting

A 43-year-old Swiss man was arrested on strong suspicion of being responsible for a fatal shooting at a rave in Aarau, Switzerland. The attack occurred in the early hours of the morning as the event was concluding at the racecourse. The perpetrator left an Italian woman, Maria Spinelli, dead and injured five others, including four Swiss men and a German woman, aged between 24 and 31.

Police are investigating the exact circumstances of the incident and believe a lone individual was involved. The cantonal police have stated that the motive remains unknown, and are considering three hypotheses: a terrorist attack, a mass shooting, or a simple criminal act. Swiss President Guy Parmelin and Swiss Justice Minister Beat Jans have expressed condolences and praised the strong cooperation between police forces.
