Police say two people are behind bars, facing charges of second degree assault, kidnapping, and threats of violence.
Officials were initially called to a Duluth hospital on Friday to interview a 21 year old man, who police say was an assault victim.
Following the interview, a 34-year-old woman and a 17-year-old girl, both of Duluth, were arrested after the investigation.
They are being held at the St. Louis County Jail and the Arrowhead Juvenile Detention Center.
Police say this was not random, and all individuals knew each other.
The incident is still under investigation.
