An extremist mob threw an Egyptian teenager off a ledge on top of a roof and beat him to death, local media reported.
The young man, identified as Hamada Badr, 19, and his three friends were caught on camera hiding from a large group who had chased them onto a terrace in Alexandria.
The video, apparently filmed with a mobile phone camera from across the road, show the four teenagers escaping onto a 20ft ledge during violent protests on Friday.
As the teenagers huddle on top of the 20ft ledge, the mob begin throwing rocks at them and attempt to climb after them.
One bearded thug is seen carrying a black and white Al Qaeda flag.
Shortly after, three of the boys are thrown off the fifth-floor ledge and beaten as they lie on the ground.
Badr, died while his two friends were left seriously injured.
His father, Mohammed Badr, said: ‘Do you know the teenager that they killed and disfigured his body and threw from the fifth floor is only 19 and four days?
‘All he was guilty of was that he was on the roof of the building, celebrating the ousting of (overthrown president Mohammad) Mursi”, the teenager’s father added.
