According to Swedish police, the couple is probably somewhere between Lekvattnet in Torsby municipality in Sweden and Kongsvinger in Norway. They were on their way to another place in Sweden when they drove away.
The last time there was contact with the couple was at 5 pm, since then the police have not been able to get hold of them.
– They have been out driving on a road, got stuck and now we do not know where they are, says police spokesman Lars Hedelin.
He describes the area the couple is in as large and difficult to navigate.
Several police patrols are on the road to search for the couple, and Swedish police are considering using a helicopter in the search. The temperature at the site is around zero degrees.
