DULUTH - A Superior woman could face assault charges after two anti-abortion protestors said she threatened them with a knife.

It allegedly happened Tuesday morning outside the Building for Women, 32 East 1st Street.  The protestors said the woman held a knife to one protestor's neck and told her to stop talking to her, and then threatened a second protestor before going in the building.  No one was injured.

Officers later arrested a 25-year-old woman, who faces two possible charges of second-degree assault.  Police say the woman had a knife in her purse.
