In 1973, suspected Mossad operative Dan Ert (Dan Ærbel) was arrested in Norway, alleged to have helped assassinate one of the Palestinian terrorists who had killed eleven Israeli athletes at the 1972 Olympic games in Munich. Ert recounted the story whilst imprisoned as a way of proving that he was a Mossad operative. The story seemed more credible once it was found that Ert had been listed as president of the Liberian shipping company used to purchase Scheersberg A.
