Turkish authorities should free Halk TV editor-in-chief Suat Toktaş and drop the charges against him and four colleagues, whose trial is due to open on March 4, the Committee to Protect Journalists said Monday.

An Istanbul court arrested Toktas on January 26 after pro-opposition Halk TV broadcast a conversation between its journalist Barış Pehlivan and an expert financial witness. The court said Halk TV had secretly recorded the two men’s telephone conversation and it had publicly named the witness to put pressure on him. Four other Halk TV staff were placed under judicial control and banned from foreign travel.

“Suat Toktaş and his four Halk TV colleagues must not be jailed for airing an interview that the government disagreed with. The public deserve to hear all sides of this story, which is of national importance and involves a top Turkish politician,” said Özgür Öğret, CPJ’s Turkey representative. “Authorities should immediately halt their prosecution of Halk TV and instead take a positive step towards improving Turkey’s dismal press freedom record.”

Pehlivan’s interview took place after Istanbul’s opposition Mayor Ekrem İmamoğlu hosted a news conference where he named the witness, who he alleged had filed biased reports in numerous politically motivated lawsuits against opposition-controlled municipalities. The witness told Pehlivan that the mayor’s allegations were false.

The interview was aired on a program hosted by Seda Selek, with Serhan Asker as director and Kürşad Oğuz as program coordinator.

All five journalists were charged with violating the privacy of communication through the press and influencing those performing judicial duties, a crime for which the prosecution has requested up to nine years in prison. Pehlivan and Oğuz face an additional charge of recording non-public conversations between individuals and could be jailed for up to 14 years, according to the indictment, reviewed by CPJ.

CPJ’s email to Istanbul’s chief prosecutor requesting comment did not receive a response.
