Five people were killed in a shooting in northern Switzerland last night.
The gunman in the shooting in the town of Wuerenlingen, near Zurich, was among the dead, Michael Leutpold, head of the local police told a news conference.
He added the shootings were linked to a personal conflict and a terrorist angle has been ruled out.
Mr Leutpold said the gunman was a 36-year-old Swiss national but did not reveal his identity.
Local media reports described him as a policeman and father of three.
He did not have a gun licence and did not fire with a police weapon, a police spokesman said.
The gunman first went to a house in a residential area and fired on three people, killing his parents-in-law and his 32-year-old brother-in-law.
He then went to another house and shot dead a 46-year-old man before turning the gun on himself.
Neighbours had alerted police after hearing gunshots after 11pm.
The shooting follows similar incidents in January and November.
According to unconfirmed estimates, there are up to 4.5 million firearms in circulation in Switzerland.
It is one of the world's top countries in terms of the circulation of firearms, after the United States, Yemen and Serbia.
