“One passenger was still in the aircraft and another was found ten minutes ago some 200 metres down river from the crash site,” said Jonny Hjalmarsson of the Arvika emergency services to the Aftonbladet newspaper shortly after 2.30pm.
The two passengers were men in their sixties hailing from Värmland county, in western Sweden.
Workers at the airstrip were the first to notice that the plane was in trouble and alerted emergency services. The craft reportedly nose-dived straight into water.
“The plane has crashed straight into a stream or something similar, with quite a lot of water, where there are fairly strong currents,” said Britt Samuelsson of the Aeronautical Search and Rescue Centre (flygräddningscentralen) in Gothenburg to news agency TT.
The plane, which weighed around half a tonne and was built to carry two people, has now been dragged to land, where police have cordoned off the area.
Local police explained that the Swedish Accident Investigation Authority (Statens haverikommission) will be launching an investigation into the incident.
