CARACAS, Venezuela (AP) — Spanish authorities acknowledge they've arrested a married couple with links to Venezuela's late President Hugo Chavez in a case of suspected corruption.

Officials in Madrid announced Wednesday they detained the pair at Venezuela's request.

The two are Claudia Diaz, a one-time nurse of Chavez who later rose to high positions, and her husband, Adrian Velasquez Figueroa, a former member of the presidential palace's security detail.

Venezuelan officials are seeking them on suspicion of corruption revealed in the Panama Papers — a document leak from a Panamanian law firm that illustrated how the powerful hide their fortunes.

Venezuelan Attorney General Tarek William Saab had announced the arrests in early April, but officials in Spain at first denied it.

A Spanish judge is expected to hold an extradition hearing Thursday.
