Eight of Turkey's most respected human rights defenders were arrested last week , along with two information technology trainers from Sweden and Germany. All ten of those arrested are still in police custody  but have not been charged with any crime.
The group had gathered for digital security and information management workshop on one of Istanbul's islands, Buyukada, on July 5 when police raided the workshop, detained the participants, and confiscated electronic equipment including computers and mobile phones. Among those arrested was the director of Amnesty International Turkey, Idil Eser.
Turkish newspaper Cumhuriyet reported  that police also raided the homes of some of the human rights defenders who was arrested, and seized books, CDs, phones and digital devices. On July 11, Hurriyet Daily News  reported that “house raids on detainees’ addresses were still ongoing.”
Amnesty International announced on July 11  that all ten people will remain in detention for at least seven more days.
Amnesty International chief Salil Shetty described  the arrests as a “grotesque abuse of power and highlights the precarious situation facing human rights activists in the country.”
Hugh Williamson, Europe and Central Asia director at Human Rights Watch, described the situation  as “a repressive new low for the Turkish state,” and called for their immediate release.
When he was questioned about the detentions at a July 8 press conference  at the G20 Summit in Hamburg, Germany, Turkish President Recep Tayyip Erdogan argued that the meeting “would constitute almost a continuation of the 15th July events,” referencing the failed coup attempt of 2016.
Turkish authorities have provided no evidence to the media or the public of the President's assertion. All ten of those detained demonstrate a commitment peaceful, constructive protection of the rights of all Turkish people as they are enshrined by local laws and international human rights norms.
Governments and intergovernmental agencies from around the world have expressed concern about a lack of due process and abuse of power on the part of the regime. Former Prime Minister of Sweden, Carl Bildt, described the arrests as a “very worrying sign”:
Very worrying sign with Turkish authorities detaining key human rights defenders. Prosecutors running amok. https://t.co/pAx3s78CX5
