BAGHDAD: The person believed to have recorded Saddam Hussein's execution on a cell phone camera was arrested on Wednesday, an adviser to Iraq's Prime Minister said.

The adviser to Prime Minister Nouri al-Maliki, speaking on condition of anonymity because he was not authorised 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,'' he said.

Iraqi state television aired an official video of the hanging, which had no audio and never showed Saddam's actual death. But the cellphone video showed the former 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.

The unruly scene aired on Al-Jazeera television and was posted on the Internet, prompting a worldwide outcry and big protests among Iraq's Sunnis. AP
