Mohammed Khater Ghamry has become the eighth person to die in an Egyptian detention centre this month after he was denied critical medical care for suspected coronavirus.
The Shehab Centre for Human Rights have said Mohammed, who was being held in Belbeis Police Station, had a high temperature and warned that other cellmates have similar symptoms.
Earlier this month the Geneva-based Committee for Justice (CFJ) reported that another detainee at Belbeis Police Station had died from suspected coronavirus.
At the time, CFJ reported that at least four detainees were suffering from covid symptoms including respiratory distress and high temperature, indicating prison authorities are not taking appropriate measures to protect or test them.
Detainee Ibrahim Mohamed Al-Daleel Okasha also died earlier this month in a hospital in Sharqiyah Governorate after being transferred there from Hahya Police Station. Ibrahim had a high temperature, a severe cough and suffered severe respiratory distress.
CFJ said authorities have failed to reveal the true cause of his death.
On 2 May Egyptian filmmaker Shady Habash died in Tora Prison after his health deteriorated and he was not given medical help.
The circumstances under which these detainees died contrasts starkly with authorities' decision to release 3,000 prisoners this weekend under an Eid presidential pardon, including those that had been jailed for theft, prostitution and fraud.
The families of political prisoners were devastated to find that their loved ones were not on the list and that criminals were released instead.
Detainees are kept in overcrowded cells, have little access to sunlight and fresh air and often have to share hygiene tools. Since the start of the covid pandemic they have been denied visits from lawyers and family members.
