A Phoenix Target was evacuated Tuesday after a man was seen pouring an unknown substance over items in the store near Ray Road and 48th Street. Store employees told firefighters the man was pouring vinegar and hydrogen peroxide together. Hazmat crews determined the liquid and the air in the store was not toxic. The 48-year-old man, identified Wednesday as David C. Lohr, was arrested and the store was immediately evacuated, according to police. No employees or shoppers were hurt. A fire prevention specialist remained on scene to help the Target resume normal operations. According to a spokesperson with Target, Tuesday's incident was connected to a series of recent food tampering attempts at six Target stores in Phoenix, Tempe, Chandler and Scottsdale.
