A senior police officer from the Interior Ministry's national security branch was assassinated late Sunday.
Lieutenant Colonel Mohamed Mabrouk was shot seven times in the chest and head. Eyewitnesses reported the perpetrators wore masks.
Mabrouk monitored Islamist groups, including the Muslim Brotherhood, within the Interior Ministry's national security agency.
Informed sources revealed that Mabrouk, killed on Sunday, was also the top prosecution witness in the lawsuit accusing deposed President Mohamed Morsy and other Muslim Brotherhood figures of escaping from Wadi al-Natrun prison during the 25 January revolution, according to Sky News Arabia.
Mabrouk had conducted investigations required by the judge into the lawsuit, which also includes accusations that Morsy spied for Hamas in the Gaza Strip.
Mabrouk’s purported evidence included phone calls that allegedly took place between Hamas figures and Brotherhood leaders in Egypt.
