Police in the Bahamas said late Wednesday that they have arrested the husband of a U.S. woman who was aboard a boat near the archipelago and vanished.

Authorities said the 59-year-old man whom they did not identify was arrested in Abaco and is being questioned.

A Coast Guard spokesperson told The Associated Press late Wednesday that they have opened a criminal investigation into the case.

Police did not provide further details, including whether or not he was charged.

Officials have said Lynette Hooker, 55, was traveling in an 8-foot motorboat from Hope Town to Elbow Cay on Saturday night, and that her husband, 58-year-old Brian Hooker, told authorities she fell overboard with the boat keys, causing the engine to turn off.
