Nihat Ürkmez, a Daesh-linked suspect in the Ankara terror attack in which 103 people were killed in October, was detained by police on Thursday in eastern Elazığ province.
Ürkmez was arrested by the Ankara Public Prosecutor's Office and sent to jail.
The Bingöl Police Department tracked down Ürkmez to Elazığ, after he was spotted with the 'courier' of the terror attack Halil İbrahim Durgun.
Media reported that Ürkmez is linked with fugitive Yunus Durmaz, a self-proclaimed DAESH "emir" for Gaziantep who was involved in both bringing suicide bombers to Ankara after receiving them from the Syrian border and the delivery of the explosives that were used in the attack.
The photos on Durmaz's computer were sent to the provincial police headquarters by the Ankara Public Prosecutor's Office.
The prosecutor's office confirmed in October that one of the suicide bombers in the terror attack was DAESH member Yunus Emre Alagöz, who was also the brother of Şeyh Abdurrahman Alagöz, the suicide bomber who conducted the deadly Suruç bombing that killed 33 people and wounded more than 100 on July 20, 2015.
The second suicide bomber was confirmed by authorities on Jan. 10, and was identified by his initials, E.U., as a Syrian national.
The twin suicide bombings in Ankara, which were the deadliest attack in Turkish history, were set off by two suicide attackers in a crowd of leftist, pro-Kurdish and union activists at a peace rally.
Previously, two suspected DAESH suicide bombers, one of them a member of the DAESH-affiliated Dokumacılar (Weavers) group, were arrested by security forces late on Friday in Gaziantep province. Four suspects were captured in the operation, according to a statement released by the Gaziantep Governorate on late Monday.
According to information obtained from security sources, a DAESH terrorist named Mehmet Mustafa Çevik was arrested along with Ercan Çapkın, the brother of Erkan Çapkın, one of the suspected perpetrators of the March 19 suicide bombing on Istanbul's İstiklal Avenue, which claimed the lives of four people. Çevik was also being sought for having links to al-Qaida. The investigation was launched after the bombing showed that Çapkın was DAESH's regional head in Gaziantep province, which borders Syria.
