Dane Andreas Hvid posted the x-rated image on his own website and in a video he later unveiled on YouTube. The footage - which has since been deleted - shows the lensman and the unnamed woman reaching the ft top and looking out over the view of Cairo below. An explicit still picture which is inserted into the video then shows Hvid on top of the woman who is lying on the summit of the 4,year-old pyramid. State news agency Ahram Online has since revealed the minister of antiquities Khaled el Anany had referred the case to the prosecutor general for investigation. He said the action was a violation of public morality and the incident and video would be investigated at the highest level.
