Swiss prosecutors raided facilities at the Geneva Free Ports on Friday, April 8, and seized a Nazi-looted Amedeo Modigliani painting. Seated Man with a Cane, which belonged to the Parisian art dealer Oscar Stettiner, has been at the center of a lengthy legal battle led by the original owner’s grandson. The current owner of the painting is the International Art Center, an investment firm owned by collector David Nahmad—a fact that was revealed in the recent Panama Papers leak.
