(CNN) -- The 9-year-old boy who sneaked onto a plane for a trip to Las Vegas is back in his hometown of Minneapolis, a family spokesman said Saturday night. Spokesman V. J. Smith would not provide details. He said he would speak with the boy's father Sunday. Crew members aboard a Delta Air Lines flight October 3 became suspicious of their child passenger and then found that he had no ticket or boarding pass. He was placed in a foster home as authorities began an investigation. The Transportation Security Administration has said the boy went through security at Minneapolis-St. Paul International Airport, although it has not explained how he did so without a boarding pass. An airport spokesman said video shows the boy chatted with a Delta agent when he reached the gate and moved toward the plane when the agent became distracted. Father: 'No one stepped up to help' 'He's got a behavioral problem,' dad says . CNN's Janet DiGiacomo contributed to this report.
