The law enforcement used video cameras during the operation, the Anadolu news agency reported.
Khashoggi went missing after entering the Saudi consulate on October 2. After weeks of denials, the Saudi authorities acknowledged that the journalist, a critic of Riyadh, was slain inside the consulate building.
More than 160 non-government organizations said in a statement on Friday that the international community must hold the government of Saudi Arabia accountable for the murder of columnist Jamal Khashoggi. The NGOs called on the United Nations to launch an independent probe into the murder of Khashoggi and suspend Saudi Arabia from the Human Rights Council.
On Monday, US President Donald Trump said he was not satisfied with the explanation of the incident put out by the Saudi government. Trump told reporters that allowing one month for an investigation, as requested by Riyadh, would be too long.
Saudi Crown Prince Mohammed bin Salman described Wednesday the case of murdered Jamal Khashoggi as "painful" for all Saudis, stressing that this heinous crime cannot be justified.
