The relatives of protesters killed during Egypt's revolution have stormed a courtroom in Suez on Thursday during the trial of police officers accused of their murder.
They acted to complain about the trial's slow place and that many of the defendants had been released on bail.
Judge Ahmed Reda adjourned the trial for half an hour until court officials were able to restore calm.
"You will not get the rights of your sons through shouting and machismo," Judge Reda told them.
Fourteen police personnel are on trial for the murder of 17 protesters in Suez during the uprising that brought down the regime of Hosni Mubarak in early 2011.
The families of slain protesters have repeatedly complained that police officers responsible for their deaths have not been arrested despite video footage and other evidence against them.
