A 61-year-old Swiss man suspected of selling arms illegally to Austria has been arrested by police in St Gallen.
During a search of a property in Degersheim last week police seized 280 weapons, over 100,000 rounds of ammunition and 1.3 million francs in cash, St Gallen police said in a press release.
Among the weapons haul were submachine guns, grenades, pistols and rifles.
The man was suspected of illegally selling arms to Austria and has been the subject of a joint investigation by Austria and Swiss authorities for the past five months.
He is now in custody, accused of threatening public safety and violating the weapons act.
