Egypt's public prosecution announced on Tuesday that it had ordered the detention of man for four days pending investigations on charges of sexually assaulting a child under the age of five.
On Tuesday morning, a video clip showing an adult man exposing himself and dragging a boy into his car went viral online, sparking anger. It was later removed by Facebook for violating its policies.
According to the public prosecution's monitoring unit, the video was filmed by a CCTV camera in New Cairo.
The prosecution added that it received a complaint from the child's mother on Saturday that, on 21 September, the suspect had dragged her son from in front of their house claiming that he wanted to play with him, and had sexually assaulted him in his car, before fleeing the scene.
The prosecution interviewed the boy and identified the suspect, who was arrested.
The prosecution has assigned the forensic authority to examine the boy and has tasked police officers to examine the video.
