Egypt's prosecution ordered on Wednesday that 25 members of the banned Muslim Brotherhood be detained for 15 days pending investigations into terrorism-related charges.
The defendants are accused of joining an outlawed group and plotting violent acts and with the aim of preventing state institutions from fulfilling their duties.
According to the Ministry of Interior, the accused individuals plotted with several leaders of the terrorist-designated Muslim Brotherhood group abroad to spread chaos and terrorise citizens with the aim of disrupting peace and public order and harming the national security.
The suspects plotted to sow chaos in the country in January and February to coincide with the anniversary of the 25 January revolution.
The accused were among 54 people arrested for plotting attacks in Egypt in coordination with the Brotherhood’s leadership abroad.
Brotherhood leaders abroad formed a group on the internet which included members of the organisation and anti-state elements inside the country under the name "O Allah, Revolution," holding a number of meetings abroad to plan the execution of their terrorist plot, the ministry said.
The ministry said that the accused were found in possession of cash and materials used in riots to block roads and set fires.
The ministry said that it is working to identify and arrest the remaining members of the group, which is reportedly led by Yasser El-Omda, a fugitive Brotherhood leader currently residing in Turkey.
