Geneva: A shooting in northern Switzerland has killed one person and injured at least five, some of them seriously, local police said on Sunday.

Cantonal police in Aargau said a manhunt was underway and they appealed to the public for any film or pictures of the incident, which the mass-market Blick tabloid said had occurred at a rave party in the hippodrome.

A video on its site recorded successive gunshots being fired. Large areas of the Aarau town are cordoned off, police said, and it has increased its presence beyond the town as a precaution.

Switzerland has one of the highest rates of gun ownership in Europe although violent shootings are rare and it approved tighter gun control rules in 2019.
