"We believe that the two individuals came to Turkey for the sole purpose of covering up evidence of Jamal Khashoggi's murder before the Turkish police were allowed to search the premises," a senior Turkish official said, asking not to be named.
The official confirmed a report in the Sabah newspaper saying that chemicals expert Ahmad Abdulaziz al-Janobi and toxicology expert Khaled Yahya al-Zahrani were among a team sent from Saudi Arabia purportedly to investigate the murder last month.
But despite intensive searches by Turkish police, there is still no trace of his remains.
Turkey's allegation of the deployment of a "clean-up" team came after Yasin Aktay, an advisor to President Recep Tayyip Erdogan, hinted Friday that the body may even have been destroyed in acid.
In an editorial published in The Washington Post Friday, Erdogan said it came from "the highest levels" of the Saudi government, while he did "not believe for a second" that Saudi's King Salman had ordered the crime.
"Yes, a murder was committed and it was premeditated. Who gave the command for this murder to be carried out on Turkish soil?" Oktay echoed the president's question in Monday's interview.
However, Erdogan has yet to directly accuse Prince Mohammed, who has condemned the murder "a repulsive incident".
The unnamed Turkish official said Monday: "The fact that a clean-up team was dispatched from Saudi Arabia nine days after the murder suggests that Khashoggi's slaying was within the knowledge of top Saudi official."
Saudi Attorney General Sheikh Saud al-Mojeb met with Turkish authorities last week in Istanbul.
But this visit appeared to be a fiasco, with the Saudi official refusing to share information from Riyadh's own investigation, according to Turkish officials.
Prince Mohammed had been heralded in some quarters before the murder as a modern Arab reformer spearheading a bold vision to transform the country and make it less dependent on energy resources.
That image has now been severely battered. There is also a new international focus on Saudi's involvement in the war in Yemen where 14 million people now stand at the brink of famine in Yemen in what the United Nations has called the world's worst humanitarian crisis.
The outrage has alarmed business leaders seeking a foothold in the crown prince's reform drive but many have insisted they have no intention of pulling out.
"As horrible as this event was, we cannot turn our backs on the Saudi people as we work to help them in their continued efforts to reform and modernise their society.
