A number of Egyptian syndicates released statements on Tuesday condemning the arrests of protesters on 25 April during demonstrations against a recent decision by Egypt to acknowledge Saudi Arabia's sovereignty over the Red Sea islands of Tiran and Sanafir.

At least 239 people were arrested at demonstrations nationwide according to Freedom for the Brave statement on Tuesday, an Egyptian activist group tracking protesters’ arrests.

On Wednesday, Egypt's general prosecution decided to keep in detention more than 160 protesters for a further 24 hours who were arrested on Monday – including 111 of those detained in the Dokki and Agouza areas alone – until investigations by National Security have concluded.

The Journalists Syndicate released a statement denouncing the continuing detainment of seven journalists, and the police’s refusal to allow reporters to approach the syndicate on the day of the protests.

They also criticised the police for allowing supporters of the government to dance on the syndicate’s steps, which was intended as the original protest venue.

The syndicate will file a complaint to the prosecution on Thursday.

The Lawyers Syndicate said its members had troubles in Qasr El-Nil and Al-Dokki Police station while attempting to represent detained protesters.

They said in a statement that they denounce all attacks on lawyers defending detained protesters and said they would not be silenced by the incidents. They will file a complaint to the prosecution in opposition to the “thuggery” against the lawyers.

Meanwhile, the Doctors Syndicate said in a statement that two of its members were arrested on 25 April after having breakfast in a downtown café before heading to start their shifts in Qasr El-Aini Hospital.

The statement also mentioned the arrest of Doctor Mohamed Adel Sultan, currently doing his residency, on 21 April from a downtown café. His arrest came during the preemptive arrests of tens of youths and activists ahead of the Monday protests.

The syndicate said it filed a report to the prosecution to free the detained doctors and called on the prosecution to stop random arrest raids on youths and release all those with no real evidence against them.

The Engineers Syndicate said it is their obligation to defend their members, regardless of their political beliefs, and called on the families of detained engineers to come forward to the syndicate so that they can send lawyers on their behalf.

It is still unclear the number of Engineers Syndicate members arrested during the protests.
