Turkish prosecutors are expected to submit the indictment on the controversial Ergenekon case by end of the week. Earlier on Tuesday retired generals, Sener Eruygur and Hursit Tolon, as well as the chairman of Trade Chamber of Ankara, Sinan Aygun, were transferred to a high-security prison in a northwestern province of Turkey from a prison in Istanbul where they were initially being held.
The retired generals and the chairman of Trade Chamber of Ankara were transferred early on Tuyesday to Kandira Prison in Kocaeli, Dogan News Agency reported.
Eruygur, Tolon and Aygun were arrested as part of the Ergenekon operation as having suspected links to a gang that allegedly planned to provoke chaos around the country to pave the way for a military coup, and sent to Metris Prison in Istanbul.
The three were transferred to F-type cells in the Kandira Prison, the agency added.
In the latest wave of the Ergenekon operation, which came on the same day the chief prosecutor presented his verbal arguments in the closure case against the ruling Justice and Development Party (AKP), 21 people were detained, including two retired generals, journalists and a prominent business leader.
Ten people were placed behind bars after a court formally ordered their arrest.
The Ergenekon organization is accused of provoking events that would pave the way for a military coup to overthrow the AKP government, although the indictment in the case and the charges are yet to be clarified.
Analysts agree that the Ergenekon operation is a new stage in the "power struggle between the AKP and hard-line secularists".
