THUNDER BAY -- A 19-year-old woman was taken to hospital early on Monday morning after an incident at an apartment in the River Street/North Algoma Street area.
Ontario's Special Investigations Unit describes her injuries as serious.
The SIU is looking into the incident, as it is mandated to do, because Thunder Bay Police had been called to deal with a domestic situation at that location.
According to an SIU news release, officers arrived just after midnight and arrested a 19-year-old man.
However the statement does not indicate what led up to the woman's fall, or when she fell.
Neither the SIU nor the Thunder Bay Police Service has disclosed the address of the building where the incident occurred.
Two investigators and one forensic investigator are assigned to the case.
The SIU is asking anyone who may have information about the case to contact the agency at 1-800-787-8529.
The Special Investigations Unit investigates all reports involving police where there has been death, serious injury or allegations of sexual assault.
