Rights campaigners have accused Egypt’s security forces of routinely carrying out unlawful executions, and then claiming that the deaths occurred during “shoot-outs” with militants.
Human Rights Watch says that the authorities have reported more than 750 such killings over five years.
However, only one arrest was made in all the so-called shoot-outs.
The campaign group closely examined 14 deaths, and found relatives saying that they knew the victims were in custody before they were killed.
The Egyptian authorities have waged a long campaign against members of the Muslim Brotherhood organisation, which they describe as a terrorist group.
