CNN said it obtained the law enforcement surveillance video that appears to show Madani leaving the diplomatic mission through the back door, wearing Khashoggi's clothes, a fake beard and glasses. Prosecutors are seeking statements from a total of 45 employees, CNN Turk said.
President Recep Tayyip Erdoğan said Sunday he would reveal the "truth" about the Khashoggi case on Tuesday while Turkish officials vowed to pursue the case after Saudi Arabia's admission of guilt.
Saudi Arabia has sought to check the fallout by arresting 18 people suspected of killing Khashoggi, dismissing two top officials and claiming the journalist and government critic died accidentally after being put in a chokehold.
Saudi Arabia says it does not know the body's whereabouts, with anonymous officials saying it was rolled into a carpet and given to a "local collaborator" to be disposed of, a claim dismissed by Turkish sources.
#MeToo Allegations: Editors' Guild Asks MJ Akbar to Drop Defamation Case
Minutes after news of Akbar's resignation broke, Ramani tweeted: "As women we feel vindicated by MJ Akbar's resignation". Several of them claimed that he had sexually harassed them, while others claimed to have witnessed it.
A separate report by newspaper Yeni Safak said Maher Abdulaziz Mutreb, a member of Prince Mohammed's entourage on trips to the United States, France and Spain this year, made the calls from the consulate.
There has been speculation Khashoggi was murdered because of his open criticism of the Crown Prince but Saudi authorities insist the royal played no part in his death.
Turkey's Anadolu agency said early on Monday that Erdogan and U.S. President Donald Trump had spoken on the telephone and agreed that "all aspects" of the case needed to be cleared up.
A Saudi official, who spoke on the condition of anonymity because they were not authorized to speak publicly, said the other fired intelligence officers were nearing retirement.
As the investigation into the death of Jamal Khashoggi continues, Turkish police on Monday found a vehicle belonging to the Saudi consulate and bearing diplomatic plates in a private parking lot in Istanbul's Sultangazi district, where it had been parked for several days after the journalist's disappearance.
Madani, 57, is of similar age and build to Khashoggi, 59, and was reportedly brought in as a decoy to throw Turkish investigators off the killers' trail.
Australia-Indonesia relationship could be 'thrown under bus' over Israel embassy comments
Labor is concerned the approach could undermine the prospect of a two-state solution between Israel and Palestine. Indonesia, the world's largest Muslim-majority nation, and Australia are due to sign a trade deal this year.
Speaking to reporters in Berlin on Sunday, Chancellor Angela Merkel announced the arms freeze and said she will continue working with global allies to coordinate their response to Khashoggi's murder inside a Saudi consulate.
Saudi Arabia has provided a shifting account of what happened to Khashoggi.
On Sunday, Britain, Germany and France issued a joint statement indicating that the Saudi explanation of Khashoggi's killing did not go far enough.
He said: "We are not going to throw our hands in the air and terminate our relationship with Saudi Arabia, not just because of the huge number of British jobs that depend on it but also because if you exert influence over your partners you need to be able to talk to them". All of them shield King Salman and his son and from any involvement.
Officials in Saudi Arabia have not answered repeated requests for comment from The Associated Press in recent days, including on Monday.
Khashoggi was killed October 2 at the consulate, where he had gone to get paperwork to be married.
