The US has called for a comprehensive investigation into the killing of an Egyptian critic.
Mr Hadhoud's death was deemed not to be the consequence of any crime by Egypt's Public Prosecution office last month.

The United States is demanding an "immediate, complete, transparent, and credible investigation" into the death in prison of Egyptian scholar Ayman Hadhoud.
On Monday, State Department spokesman Ned Price said that news of his alleged abuse while in captivity had greatly concerned the US.
He stated that his administration had continued to push Egypt to prioritize the protection of human rights.
Mr. Hadhoud's death was deemed not to be the consequence of any crime by Egypt's Public Prosecution office last month.
He died of a longstanding heart problem, according to the report, and there were no signs of violence or resistance.
Mr. Hadhoud, a government opponent, died in a state-run psychiatric facility in March, but his remains were not returned to his family until earlier this month.
His supporters claimed that following his "forced disappearance," he was subjected to ill-treatment by the authorities.
