Swiss police arrested a man found with traces of explosives outside the country's parliament on Tuesday, sparking a security alert that shut down part of Bern for several hours.
The man, who has not been named, was stopped by security officers because of his suspicious behaviour and appearance early in the afternoon.
Officers were alerted after seeing the man, a 27-year-old from the Swiss canton of Valais, wearing a protective vest and a gun holster.
