She was heavily intoxicated and was taken to the hospital directly, says the police's press spokesperson Magnus Jansson Klarin.
There is no update on the woman's condition at present.
The woman is believed to have been at a restaurant in Köping and left it at around 1 am. After that, it is unclear where she went, according to Jansson Klarin.
At 9 am on Sunday morning, the woman was found by passersby, partially under a car, in a parking lot.
The police cordoned off the area for technical investigation, conducted door-to-door inquiries in the area, and searched with a dog.
We are seeking observations and will analyze the technical parts we have and hear the woman herself, says Jansson Klarin about how the investigation will continue.
On Monday, there is no suspect detained.
