PARIS — Officials say an FBI tip helped French police track down and arrest an 87-year-old American and his wife who are wanted by U.S. authorities — more than a year after they quietly settled near a bucolic Alpine lake.

Regional state prosecutor Patrice Guigon said Friday that former Seattle real estate developer Michael Mastro and his wife, Linda, will remain in custody at least until a judge rules Nov. 7 on their lawyer's request for their provisional release.

French police arrested the couple Wednesday at their apartment in the town of Doussard, near Lake Annecy. They face a 43-count grand jury indictment, including allegedly lying about the whereabouts of two huge diamonds valued at $1.4 million as part of a bankruptcy proceeding.

Mastro owes more than $200 million to creditors.
