The man suspected of shooting dead an Italian woman at a rave party in Switzerland is suffering from “psychological problems” and has remained silent in custody, prosecutors have said.
Gunfire erupted in the early hours of Sunday morning as an annual rave was winding down at the racecourse in Aarau, capital of Switzerland’s northern canton of Aargau.
The attack left a 22-year-old Italian woman dead and wounded five others, some seriously.
A 43-year-old Swiss man handed himself in to police in Delemont, in northeastern Switzerland’s Jura canton.
He is suffering from “psychological problems” and has maintained his silence since his arrest on Monday, the Aargau cantonal prosecutor Christoph Ruedi told a press conference.
The Aargau police said that two pistols and an AK-47 assault rifle were found in the suspect’s car.
Police chief Michael Leupold said the motive for the attack remained unclear, adding that the suspect was not previously known to the police and had no known links to extremist movements.
The police said the shooter acted alone and fired around 40 rounds before fleeing in his car.
Those hurt were four Swiss men and a German woman, aged between 24 and 31.
They were taken to hospital “with injuries ranging from minor to serious”, police said.
Shootings are rare in Switzerland, despite widespread gun ownership.
The rave organisers said they were “devastated”, saying on their website that “the insidious attack on the guests at the Aarauer Rave has broken our hearts.”
“A rave should always be a place of joy and love. Never a place where people are killed, injured or left in fear.”
