Two Muslim Brotherhood members accused of throwing teenage boys from a rooftop in Alexandria have been detained for 15 days pending investigations, state news agency MENA reported.
A teenager was killed after supporters of ousted president Mohamed Morsi threw him off a ledge on a rooftop.
The defendants admitted the crime and were detained for four days before a judge extended their detention on Thursday.
A video of the incident – which went viral online – shows a mob cornering four teenage boys on top of a water tank then throwing two of them from the six metre-high ledge. The boy who died was severely beaten as he lay injured. The other suffered injuries.
The incident, which sent shockwaves across the country, took place in Alexandria's Sidi Gaber district on Friday, a day of violent clashes following the overthrow of Mohamed Morsi.
The incident reportedly erupted when the teenagers threw stones from the rooftop at pro-Morsi protesters on the street below.
The dead boy's father said his son was merely celebrating Morsi's ouster.
