Nov. 30 (UPI) -- Holocaust survivor organizations have called on the Polish government to explain how a group of artists gained access to a Nazi gas chamber and filmed themselves playing tag in the nude.
A letter from the organizations -- which include the Organization of Holocaust Survivors in Israel and the Simon Wiesenthal Center -- asked President Andrzej Duda to determine how the group of artists gained access to the Stutthof gas chamber near Gdansk.
The video, titled Game of Tag, was shot inside the gas chamber in 1999 and was displayed in an exhibit in 2015 in Krakow. The film faced criticism for being offensive.
The museum removed the video, but later reinstated it, citing freedom of artistic expression.
The groups sent the letter after research determined the exact location of the video's setting. Experts were able to identify the specific gas chamber after comparing the video to photos from Britain's Prince William and Kate Middleton's visit to Stutthof in July.
"Extensive research recently revealed that the site where the video was filmed is the gas chamber at the Stutthof concentration camp, and it is this discovery which prompted the demand for clarifications from the Polish leaders and the administration of the Stutthof concentration camp site," the letter read.
The organizations asked if the group of artists obtained permission to film inside the gas chamber, and "what rules exist for proper conduct at the site" and how they are enforced. The letter also asked if an investigation by the government had been carried out.
