The woman was found at around 9.40pm after a car driver noticed her by the side of the E4 southbound outside of Uppsala, according to the local Uppsala Nya Tidning (UNT) daily.
“We went there and found her bound and left at the location,” said Tommy Karlsson, Uppsala county police officer.
The woman was taken to hospital to asses the extent of her injuries. Police are meanwhile attempted to locate an interpreter to establish what has happened to her.
The woman was dumped leaning by a fence around 500 metres north of Mora services.
“She was presumably dumped there from a car,” Karlsson told UNT.
According to the newspaper the woman is originally from Mongolia and she will be interviewed by police on Wednesday morning.
