Police in Salla, in Finland’s Lapland region, are asking the public for help to find a German woman in her 50s who has been reported missing.

The case began when authorities received a report on Monday of a passenger car in the water with no one inside. Investigators say they have not ruled out that the woman may still be in the water, while another possibility is that she got out and left the scene on foot.

Police believe the car was driven by a German woman with dark-brown, medium-length hair. The search is being carried out together with rescue services and border guard officials, and is expected to continue on Wednesday.

Authorities have appealed for tips and possible sightings, directing people to contact the police via email, phone, or WhatsApp.
