Japanese police say they have released an American man nearly 20 days after his arrest for allegedly snatching his children from his ex-wife.

Police said Thursday that while prosecutors have not pressed charges, they haven't yet dropped the case either. They decided to release him on grounds that he was not a flight risk.

Christopher Savoie was arrested Sept. 28 after allegedly grabbing his two children, ages 8 and 6, from his Japanese ex-wife as they walked to school in southern Japan. The case is among a growing number of custody disputes involving a foreign parent in Japan.
