The person believed to have recorded Saddam Hussein's execution on a cell phone camera was arrested Wednesday, an adviser to Iraq's prime minister said. The adviser to Iraqi Prime Minister Nouri al-Maliki, speaking on condition of anonymity because he was not authorized to talk to the media, did not identify the person. But he said it was "an official who supervised the execution" and who is "now under investigation." "In the past few hours, the government has arrested the person who made the video of Saddam's execution," the adviser said. Iraqi state television aired an official video of the hanging, which had no audio and never showed Saddam's actual death. But the cell phone video showed the deposed leader being taunted in his final moments, with witnesses shouting "go to hell" before he dropped through the gallows floor and swung dead at the end of a rope.
