The president’s son, Teodoro Obiang Mangue, was reportedly absent during the search by anti-graft police who were met with some resistance from occupants who claimed the building was protected by diplomatic immunity.
The 1,000-square metre (over 10,000 square foot) apartment in a six-storey mansion is on the chic Avenue Foch in Paris’s expensive 16th arrondissement.
President Obiang in 2010 criticised a French court’s decision to approve a corruption probe into his assets.
The appeals court ruled that magistrates could investigate the source of money spent in France by Obiang, Congo-Brazzaville’s President Denis Sassou Nguesso, and Omar Bongo, the late president of Gabon.
