Sioux Falls Police Information Officer Sam Clemens says an argument between a boyfriend and girlfriend on early Friday morning at Wal-Mart on South Louise Avenue turned violent!

"At the time, the two were arguing about their relationship. At one point, she pulled out a screwdriver and stabbed him in the arm. We had witnesses that saw the two of them together and they fell down. He took off and left. She stayed behind. They talked to her initially and she said nothing had happened. Police found the boyfriend at an apartment and he made the comment that she stabbed him with a screwdriver. Police later found the tool. She tried to throw it away in a bathroom and hide it."

Clemens says 31-year-old Julia Fawn Frazier of Sioux Falls was arrested and charged with aggravated assault domestic.

The injury to the boyfriend was not serious.
