The woman’s body was found by construction workers in the central Swedish town at 10.30 am. She was naked and had sustained a head injury.
The workers discovered the body behind a storage container after they had first come across some clothing, a handbag and traces of blood, Dala-Demokraten reports.
The family of the alleged victim has not yet been informed of the death and police spokesman Sven-Åke Petters was reluctant to comment on her age.
“It was a young woman. I can’t say any more than that,” he told news agency TT.
Police have begun a forensic examination at the scene.
