A 25-year-old California woman was arrested last week at the Minneapolis/St. Paul International Airport, after police discovered $640,000 worth of black tar heroin in a false compartment at the bottom of her suitcase.  The woman, who has remained anonymous, had allegedly made plans to transport the drugs from Los Angeles to Minneapolis, police acting on a tip apprehender her, and after searching her luggage discovered the stash of dope, weighing 4.4 pounds. She was arrested for drug possession and handed over to DEA custody.
