Interrogations with two suspects belonging to Ansar Bayt al-Maqdis revealed that they, along with others, were gathering information about security measures at Borg al-Arab Prison where toppled President Mohamed Morsy was detained and recorded the security measures on video.
The two suspects were arrested on Wednesday after the prosecutor ordered their detention for 15 days pending investigation over charges of joining a terrorist group, murder, possessing weapons and targeting police and army personnel.
Security and judicial sources said they were arrested in Alexandria and a CSF officer was killed while attempting to arrest them. Two fugitive former police officers implicated in the assassination attempt of Interior Minister Mohamed Ibrahim and a Cairo University bombing are also members of the cell, along with the arrested suspects, the sources added.
