Security forces arrested five members of Rebel (Tamarod) at a protest in Aswan on Tuesday, a member of the group's executive office has told Ahram Online.

The demonstration was organised in front of Aswan's security directorate to denounce the dispersal of a protest outside the Shura Council in Cairo earlier that day.

Abdallah Youssef said security forces asked the demonstrators – numbering around 100 – to disperse, then arrested five Tamarod members who announced the crowd would not leave. They were later released, he added.

Since a controversial protest law was issued on Sunday, police can disperse protests that have not been given prior permission by the authorities.

Particularly controversial articles include requiring protest organisers to notify authorities three days in advance of a demonstration, and imposing heavy jail terms and fines on individuals who break the law.

Security officials can cancel a protest if they obtain information showing it will threaten security and public peace, a provision widely seen as paving the way to restricting the right to protest.

On Tuesday, a few hundred demonstrators gathered at the Shura Council in Cairo to protest against an article in the draft constitution permitting the military trial of civilians. At least fifty were arrested when riot police dispersed the gathering. Some of them were later released, with scores abandoned on a desert highway.

Tamarod spearheaded the 30 June mass protests that led to the ouster of Islamist president Mohamed Morsi on 3 July.
