According to a statement issued by the prosecution, the report of the Forensic Medicine Authority stated that the body of late Haddoud did not have any traces of any injuries that may indicate criminal activity, violence, resistance, or any other suspicious indications.

The investigation also did not find any traces of drugs or poisonous substances in the deceased’s system.

Furthermore, the statement added that the prosecution listened to the testimony of the deceased’s brother, Omar, who suspected foul play after seeing traces on his brother’s body but could not determine whether it was done by the autopsy or another party.

According to the statement, Omar said that Ayman was going to receive treatment in a hospital due to psychological and nervous problems caused by financial troubles as well as the illness of their sister, however, he postponed his treatment.

Omar also asserted his brother had previously suffered twice from psychological episodes like the one leading to his arrest in February, the statement added.

According to the first statement issued by the prosecution, the late economic researcher was arrested on 6 February after he was reported by a building guard in Zamalek, Cairo for attempting to break into an apartment, adding that Hadhoud was displaying “erratic” behaviour at the time.

The death of Hadhoud has stirred controversy over the past few days amid reports that he was the victim of “forced disappearance”, with his family saying that they were notified about his death on 9 April, nearly one month after he died.

A co-founding member of the liberal Reform and Development Party said in a statement issued last week  that Ayman Haddoud was going through difficult psychological conditions that led him to “many unbalanced behavioural patterns.”

On Monday, MP Rawya Mokhtar of the Reform and Development Party demanded an inquiry in the parliament on the conditions of detention at psychiatric hospitals following the death of Haddoud during his detention at Al-Abbasiya psychiatric hospital in Cairo.
