Swiss police have launched a nationwide manhunt after a shooting at a techno rave near Aarau killed 22‑year‑old Italian national Maria Spinelli and injured five others.

The violent incident, which began at approximately 02:30 local time, took place at the Schachen horse‑racing track, a venue expected to host up to 3,500 patrons. Spinelli was killed at the scene, while four men and a woman aged 24‑27 suffered injuries ranging from minor to severe.

Arau cantonal police spokesman Michael Leupold confirmed that the investigation is in progress and there are no leads on the perpetrator’s identity or whether the shots were fired by one individual or a group. He emphasised that the police force has no knowledge of suspects remaining within Aarau.

Italian Prime Minister Giorgia Meloni assured that Swiss authorities would “shed full light” on the incident and take legal measures against those responsible. Italy’s foreign ministry dispatched officials to Zurich to closely follow the investigation, and the Italian Embassy in Bern, as well as the Consulate in Zurich, are monitoring the situation.

Authorities cordoned off a broad area around the racing track, a nearby swimming pool, and sports field, urging the public to stay away. Armed police, including officers in riot gear, patrol the streets and a Swiss Army helicopter was seen surveying the scene in the early hours.

The event organisers, represented by Agency Events AG, expressed that they are shaken and will support the police investigation. Stage performers echoed the tragedy, with one DJ describing the shooting as occurring “straight after our set,” and another expressing grief over the loss of a friend.

Evidenced by alarm footage and calls to the police for photos and videos, the incident has prompted widespread coverage and concern across Europe. Switzerland, in 2024 recorded among the highest rates of gun ownership in Europe, still experiences relatively rare violent shootings, with the most recent major case occurring in 2001.
