When they arrived at the store, they located a 24-year-old female victim who had sustained a substantial cut to her hand from the stabbing, Staff Sgt. Del Byron said Monday, adding the victim was known to the offender.
A 42-year-old woman was arrested and later released on a promise to appear in court, Byron said.
