Paolo Gabriele, a layman who lives inside Vatican City, was arrested Wednesday with secret documents in his possession and was being held Saturday, the Vatican spokesman the Rev. Federico Lombardi said in a statement.

Gabriele is often seen by Pope Benedict XVI's side in public, riding in the front seat of his open-air jeep during Wednesday general audiences or shielding the pontiff from the rain. He has been the pope's personal butler since 2006, one of the few members of the small papal household that also includes the pontiff's private secretaries and four consecrated women who care for the papal apartment.
