Turkey's top judicial body decided to start an investigation into three prosecutors and a judge who issued the court orders for the arrest and freezing of assets of suspects targeted in a series of Istanbul-based graft probes launched late December, Anadolu Agency reported.
The High Council of Judges and Prosecutors, a supreme judicial body that has the mandate to inspect and examine judges and prosecutors in Turkey, approved a request to start an investigation into prosecutors Zekeriya Oz, Celal Kara, Muammer Akkas and judge Suleyman Karacol on Friday.
The decision to start the investigation requires the ratification of Justice Minister Bekir Bozdag for approval.
Two Istanbul-based anti-graft operations launched on December 17 and 25 have had a significant effect on Turkey's political atmosphere after they led to the arrest of high-profile figures considered to be allies of the government.
The Turkish government decried the probes a "dirty plot" against it, constructed by a "parallel" group of bureaucrats that it said were nestled within the country's key institutions including judiciary and police, targeting Turkey's stability and development.
The group, allegedly run by a movement led by US-based Turkish Islamic preacher Fethullah Gulen, has been accused of conducting illegal wiretappings of thousands of people in Turkey.
