Police say 34-year-old Ronald Harris, who has worked on the Memphis police force for 12 years, was arrested Saturday and charged with robbery, aggravated assault, resisting arrest and evading arrest.
The Associated Press cited police and an affidavit in reporting that Harris apparently followed a Make-A-Wish volunteer into the Memphis airport and grabbed a bag that contained a pre-paid Visa worth $1,500 and five St. Jude T-shirts.
Police say the father of the family struggled with Harris and, with help from bystanders, got the bag back.
Harris was due in court Monday. It wasn't immediately clear if he had an attorney.
