Ankara, Oct 20 () - One of the two suicide bombers in the Oct.10 Ankara Massacre was Yunus Emre Alagöz, the brother of Şeyh Abdurrahman Alagöz, who was the perpetrator in the Suruç suicide attack that killed 33 members of a socialist youth group and wounded more than 100 on July 20, the Ankara Chief Public Prosecutor’s office announced on Oct. 19.

“One of the perpetrators of the twin Ankara bombings has been identified as Yunus Emre Alagöz,” the prosecutor said in a written statement.

“The other suicide bomber was confirmed by a photo image and a series of tests have been carried out to identify him or her” he added.

Hürriyet Daily News reported on Oct. 18 that the Alagöz brothers, along with at least 16 other suspects, were in a group probed for their links to the al-Qaeda and the Islamic State of Iraq and the Levant (ISIL), and they were under wiretap surveillance within the framework of an investigation into al-Qaeda since September 2013.

But the suspects, who are listed in the roster of wanted suspects prepared by the national police force and the National Intelligence Agency (MİT), were cleared in the investigation into the group known as “Dokumacı” group in the southeastern province of Adıyaman.

The prosecutor’s office also said four people were detained for their activites on Twitter, allegedly writing about the Oct. 10 attack before it happened. Three of them were released and one was banned from traveling abroad, according to the prosecutor.

The statement also said 20 other people were probed for their alleged links to the suicide bombers, 11 were detained, and four of them were later arrested.

Nine suspects disappeared “because of the the irresponsible publications that identified the suspects by their initials” according to the prosecutor office.

The statement came hours after an Ankara court removed a broad media ban over the investigation into the Ankara suicide attack imposed on Oct. 14.

In the raids on the homes and workplaces of the suspects, the police seized 10 suicide vests, 60 kilograms of TNT and more than 1,500 kilograms of ammonium nitrate, often used in improvised explosive devices, the prosecutor's office said.

Two suicide bombers targeting a peace rally in the capital Ankara on Oct. 10 killed at least 102 people, wounding hundreds of others.
