US authorities seize Schiele artworks from museums amid claims they were stolen from Jewish collector during Holocaust

Three artworks by Austrian Expressionist Egon Schiele were seized from the Art Institute of Chicago, Carnegie Museums of Pittsburgh, and Allen Memorial Art Museum.
The artworks were owned by Fritz Grunbaum, a Jewish cabaret performer who died in the Dachau concentration camp in 1941.
Grunbaum's heirs believe the artworks were forcibly taken from him and have been trying to reclaim them through US courts.
The seizures were carried out by the Manhattan District Attorney's office through warrants claiming the museums possessed stolen property.
The heirs previously dropped claims against the Santa Barbara Museum of Art for another Schiele artwork they believed was stolen from Grunbaum.
