According to a police press release, the toddler was alone when he walked into Sully's Pub and Grill Sunday afternoon. He told police his age and name and his father's name.
Idaho State Police found the father at a Walmart in a nearby town. Police said he appeared to be under the influence and offered no explanation about how he became separated from the child.
The 36-year-old father, identified by Coeur d'Alene Police as Jesse Edwards, has been arrested on suspicion of child endangerment. Officials said that the child's mother had not contacted police by late Sunday.
