Jason Gandy, 35, was stopped by immigration officers after he and a 15-year-old boy landed in London. Both were returned to Houston and met by Homeland Security.
Investigators say Gandy was running a massage business out of his home and was using the boy to give sexual massages. They say Gandy had also molested him.
If convicted, Gandy faces 10 years to life in prison and a large fine. He is considered a flight risk and is being held in jail without bond.
