COLLIER COUNTY, Fla.- The Collier County Sheriff's Office arrested 22-year-old Christopher Harris, a pharmacy technician, for allegedly stealing drugs from Walgreens, his former employer.

A Loss Prevention Representative from Walgreens, located at 4747 Golden Gate Parkway, told deputies Harris had recently failed a drug test, and tested positive for hydrocodone. During an interview about the failed test, Harris allegedly admitted to Loss Prevention that he had been stealing the narcotic from the pharmacy for the last six months. Harris provided Loss Prevention with a written statement. The total amount taken was $609.

Deputies met with Harris, who told them he suffered from chronic knee pain from injuries sustained during high school lacrosse and during service in the U.S. Air Force.

At the conclusion of the interview, Harris was arrested and transported to the county jail without incident.
