Inspector Colin Catonio of Lethbridge police says the woman was kidnapped on Wednesday night, then was dropped off in Calgary early Thursday morning.
The woman flagged down a Calgary police officer, and she was taken to hospital to be checked out, but wasn't injured.
Police say a relative reported the woman missing when they found her vehicle abandoned, but still running, in a neighbourhood in the west part of Lethbridge.
Catanio says the woman is being unco-operative, likely because she fears for her safety.
He says the kidnapping was targeted and connected to organized crime, so there is no threat to the public.
