Authorities say the incident started shortly before 5:00 Tuesday evening at a home on 19th street.
When police arrived they say the 50-year-old woman would not come out of the home and more officers were called in to help. Police say eventually the woman came out and needed to be treated for self-inflicted stab wounds.
Police say the incident appears to have stemmed from an argument over living arrangements.
Authorities say they are looking at referring charges against the woman to the Manitowoc County District Attorney.
