Turkish security forces detained 38 suspects during a security operation in Turkey's western province of Izmir, targeting the outlawed "parallel state" structure early on Friday.
The operation was launched following an arrest warrant for 52 suspects, including people from various occupations over links to the outlawed group.
The police are continuing their search for the remaining 14 suspect.
The “parallel state” is purported to be comprised of a group of bureaucrats embedded in the country's institutions, including the judiciary and police force, who are suspected to be part of the "Gulen movement" led by US-based Turkish preacher Fethullah Gulen and his supporters which the Turkish government alleges are plotting to undermine it.
An extensive investigation into the group began following accusations of an attempt to overthrow the elected Turkish government through a judicial coup last December.
An exclusive circle within the Gulen Movement was also determined to be a national security threat for Turkey by the National Security Council.
Meanwhile, the police also detained 11 suspects over links with the "parallel state" structure early on Tuesday during simultaneous operations in four provinces of Turkey.
The suspects were charged with spoofing public funding and providing financial sources to the illegal organisation.
