Christopher Savoie, an American freed Thursday from a Fukuoka Prefecture jail after being arrested for allegedly trying to abduct his children to regain custody, flew back to the United States Friday after promising prosecutors he would not contact his kids without going through lawyers, his lawyer said Friday.

"I recommended to him to go back home, take a rest and take the next actions — and he agreed," said lawyer Tadashi Yoshino, who represented the Tennessee native during his incarceration.

Asked what Savoie's next actions should be, he said it could be to consult a family court in Tennessee to make custodial conditions more favorable to his former wife, Noriko, so she can keep from breaking the arrangement this time, or sue for custody in a Fukuoka family court.
