A woman pushing her newborn son in a shopping cart was injured in a freak shooting incident at a Walmart store in Columbus, Ind., according to local media reports.

Police say a .22-caliber pistol fell from the pants of Tony E. Ward on Saturday evening. When the gun hit the floor, it discharged. The bullet missed the baby, but hit a bottle of soda in the cart, then ricocheted and struck the woman in the upper arm -- and it all happened while the local chief of police was in the store, according to WBIW.

Police chief Jon Rohde called for help for Virginia Thompson, 26, who was treated at the scene but she did not wish to be taken to a hospital, WHAS11 reports.

Ward, 56, had a permit for the weapon and will not be charged with a crime, Columbus Police Department spokesman Lt. Matt Myers told The Republic newspaper.

It's at least the second accidental shooting in a Walmart this month. On May 17, a shopper at a Walmart in Phoenix accidentally shot himself in the leg.
