Egyptian police say they have arrested a suspect in a drive-by shooting that seriously wounded a protester in Cairo's central Tahrir Square, where an open-ended sit-in is taking place.
According to witnesses, gunmen before dawn on Monday seriously wounded 19-year-old Muhanad Samir, who has said he was jailed and tortured under Egypt's former ruling military council after he witnessed the killing of another activist.
Lawyers say the attacked appeared to target Samir, who is battling for his life with pellets embedded in his head.
Officials said Tuesday they arrested a cafe owner who told police that he fired on the square after people manning makeshift checkpoints there searched his car and shot at him. Police suspect two others were with him.
