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.
