"The exact circumstances and reasons for the theft are the subject of an ongoing investigation by the Zurich cantonal police in cooperation with the public prosecutor's office... Kunsthaus Zurich is offering a reward of up to 10,000 Swiss francs for information leading to the investigation of the crime or the return of the paintings," the police said.
In January, the museum officially confirmed the loss of two paintings, "Soldiers at an encampment" by Flemish artist Robert van den Hoecke, dated to the middle of the 17th century, and "Daffodils and other flowers in a glass vase on a marble slab" by Dutch artist Dirck de Bray from 1673. The paintings may have been lost following a fire in the summer of 2022, the museum then said.
