The youngest son of late Egyptian President Mohammed Morsi died of an alleged heart attack Wednesday at a hospital in Cairo.

A Morsi family sourced confirmed Abdullah Morsi’s death to news agencies. However, the Egyptian Health Ministry has yet to comment on his death.

Abdallah Morsi, 24, began to feel spasms while driving in Cairo with a friend and died shortly afterwards, his brother Ahmed told Reuters.

Mohammed Morsi, Egyptian first democratically elected president, died in June while standing trial for politically-motivated charges.

Days after his father died, Abdullah identified several figures, including current Interior Minister Mahmoud Tawfiq, his predecessor Majdi Abdel Ghaffar as well as Mohamed Shereen Fahmy, the judge who oversaw the ex-president’s trial, as “accomplices” in the “assassination of the martyr, President Morsi”, Middle East Eye reports.

Morsi collapsed at a court session on 17 June after suffering six years in prison in solitary confinement where he was consistently denied access to medical care for his diabetes, hypertension and liver and kidney disease.

Morsi was elected president after the January 25 Revolution toppled Hosni Mubarak, but he was deposed by the military general turned President Abdel Fattah Al-Sisi one year later.

Despite claims from the Attorney General that Morsi was “transported immediately to hospital,” witnesses told the British newspaper the Independent that “no one bothered to help.”

“He was left slumped for while till the guards took him out. An ambulance arrived after 30 minutes. Other detainees were first to notice his collapse, they started shouting. Some of them, who are doctors, asked the guards to let them treat him or give him first aid,” said Abdullah Al-Haddad who was at the court to support his father and brother who were also on trial that day.

There are approximately 60,000 political prisoners in Egypt. Many have died from lack of access to appropriate medical care.
