Police in southern New Jersey say they are not filing charges against a man who says he believes an online photo of his young son with a rifle led child welfare workers and police to the family’s home.

Police in the town of Carneys Point said Wednesday that they went to the home of Shawn Moore with caseworkers last week after getting a tip that his 10-year-old son may have had access to guns and ammunition.

Moore says he believes the response was due to a photo he posted on Facebook of his son Josh holding a .22-caliber rifle that looks like a military-style assault rifle.

Moore says the gun was a gift for the boy’s upcoming 11th birthday.

Carneys Point is about 30 miles southwest of Philadelphia
