Approached by Al Jazeera, both the ministries of interior and information refused to comment.
However, Minister of Interior Mohamed Ibrahim has denied claims of torture. Interviewed in a talk show on a privately owned channel on February 20 Ibrahim said, “It’s impossible that any form of torture is taking place in Egyptian prisons.”
He also affirmed that no one is arrested arbitrarily in Egypt; they were either participants in "non-peaceful protests or possessed weapons."
In one of the leaked accounts, a prisoner describes how he was arrested last November.
"I saw a man dressed in civilian clothing. I asked him, ‘What’s going on? He asked me to which organization I belonged. I told him I don’t belong to anyone," he said in this video.
"He then pulled out a baton and beat me. He forced me on my knees, and as I turned my face the other way I saw one student fall to the ground as he get shot in the face with birdshot. His friend who was walking with him had his face covered in blood too, but the police still beat him," the prisoner added.
Al Jazeera has been able to verify the authenticity of the accounts, and they corroborate testimonies of former prisoners who spoke to Al Jazeera about dire conditions in Egypt's incarceration centers.
According to Wiki Thawra, an initiative by the Egyptian Center for Social and Economic Rights to document events in Egypt since the revolution of January 25 2011, more than 21,317 people were detained or faced arrest by Egyptian security forces between July and December 2013.
As anti-coup protesters, mostly supporters of ousted President Mohamed Morsi and his Muslim Brotherhood, continued to stage daily protests in the capital and elsewhere, the government vowed to get tough with what it saw as threats to national security.
The Muslim Brotherhood was designated a terrorist group on December 25, and more people were brought to prison.
This, along with an anti-protest law that drove liberal opposition to the streets, has been the pretext for many political prisoners to land in Egypt's more than two-dozen confinement camps, as well as police stations.
A decree issued by interim President Adly Mansour last September said that any suspect charged with crimes carrying the death sentence or life imprisonment can be locked in pre-trial detention indefinitely. This decision, seen by human right groups as punitive detention, has also contributed to the inflation in the number of political prisoners.
According to Wiki Thawra, 4,809 were arrested during the one-year tenure of Morsi. No records were available for any previous years.
