A colleague from the Netherlands has been in touch today about the theft of the Egyptian antiquities from the Bijbels Museum in Amsterdam.
She / he indicates that that the items were recovered from a named auction-house in New York. They indicate that my hunch was correct.
The antiquities themselves are reported to be in the possession of ICE. However as the insurance company paid out money against the claim the items are now their property. (The money was apparently spent on enhanced security.) It is hoped that the insurers will either donate the items or offer them back to the museum for a nominal sum.
