Man arrested after Swiss rave shooting that killed woman

A 43-year-old Swiss man has been arrested following a shooting at a rave in Switzerland in which a woman was killed.

Italian 22-year-old Maria Spinelli was killed and several others injured at a techno rave being held at a horse racing track in Aarau, a town about 46km (29 miles) west of Zurich on Sunday.

The shooting initiated a nearly 24-hour manhunt before Aarau cantonal police confirmed they apprehended the suspect shortly before 01:00 local time on Monday (23:00 GMT on Sunday).

"The investigation into the exact sequence of events, the background and the possible motive is currently under way," police said in a statement. "At this time, it is assumed that the perpetrator acted alone."

Police first received a report of shots fired at the Schachen race track at about 02:30 local time on Sunday.

Spinelli died at the scene, while four men and a woman, aged between 24 and 27, were taken to hospital with injuries "ranging from minor to severe".

An eyewitness told Swiss news outlet Blick that he had "suddenly heard the gunshots" minutes after the music stopped, initially believing they were fireworks.

He said he was told to hide by a man and a woman, the latter of whom was shot.
