Istanbul ( CNN ) -- A Turkish prosecutor has openly accused police of interfering with a high-level corruption investigation . `` Court orders have not been carried out and there has been open pressure on the judicial process from both the chief prosecutor 's office and from the police force , which is supposed to carry out the decisions of the courts , '' Muammer Akkas said in a Thursday statement . He spoke one day after three Cabinet ministers resigned their posts , after their sons were arrested or temporarily detained in an anti-graft sting , semiofficial news agency Anadolu reported . One of them , Urbanization and Environment Minister Erdogan Bayraktar , went further than the other two , not just resigning his Cabinet position but also calling on Prime Minister Recep Tayyip Erdogan to step down . Turkish media reported a possible second wave of detentions as imminent late Wednesday , but the raids did not materialize . Instead , an apparent deadlock within the judiciary emerged as Akkas , the prosecutor , issued his statement saying the judiciary was under the heel of the government . Akkas accused police and prosecutors of ignoring a decision of the courts by refusing to carry out more raids . In a televised statement , Chief Istanbul Prosecutor Turan Colakkadi fired back , saying that Akkas had mishandled the investigation and leaked information to the press , leading to his removal from the case . Economy Minister Zafer Caglayan and Interior Minister Muammer Guler , whose sons were also arrested in the investigation , also resigned Wednesday . Erdogan accepted the resignations , Anadolu reported . The sons were detained in a roundup that included the head of a public bank , several bureaucrats and high-profile businessmen . The roundup came after a two-year investigation by the Istanbul Prosecutor 's Office into allegations of corruption including money laundering , gold smuggling and bribery . Many analysts see the corruption investigation as a public fight between Erdogan and Fethullah Gulen , an Islamist preacher living in self imposed exile in Pennsylvania . Erdogan has repeatedly said since the corruption arrests began that international organizations with branches inside Turkey are trying to destabilize the country . `` This country has never been and never will be the operational space of international organizations . We will not allow the interest lobby , the war lobby , the blood lobby to carry out an operation under the guise of a corruption operation , '' he said Sunday . Turkey is expected to hold local elections next year , and some analysts see the raids as a test of Erdogan 's grip on power , especially after a turbulent year of unprecedented anti-government protests . Demonstrations continued Thursday , with marches in Istanbul , Mersin , Izmir and Adana , where police used water cannons on marchers . Protesters chanted : `` The ministers are thieves , '' `` Everywhere is bribery , everywhere is corruption , '' the `` Public will clean this dirt '' and the `` Prime Minister is a thief . '' The Prime Minister had been expected to reorganize his Cabinet , because some of his ministers will be running for office in March . Late Wednesday , he announced a Cabinet shuffle , naming 10 new people . After the announcement , former Culture Minister Ertugrul Gunay tweeted his displeasure . `` I wish success to the new members of the Cabinet . I will suffice to say for now that I do n't find the choices for Justice and Interior positions suitable , '' he wrote Wednesday . One day later , he and two other members of parliament -- Izmir MP Erdal Kalkan and Ankara MP Haluk Ozdalga -- were sent to Erdogan 's ruling Justice and Development Party 's disciplinary committee with a request for their dismissal . According to Anadolu , the party announced it is taking this disciplinary action against three of its members for `` disparaging remarks '' against its ideals and core policies .
