Footage obtained by Turkish broadcaster A News late Monday showed Saudi consular personnel burning documents a day after Jamal Khashoggi's disappearance.
The footage purportedly recorded in high-rises surrounding the consulate's compound in Levent district of Istanbul, shows two men burning papers in a trash container.
Khashoggi went missing on Oct. 2 after he entered the Saudi Consulate in Istanbul.
After days of denying to know his whereabouts, Saudi Arabia on Saturday claimed Khashoggi died during a fight inside the consulate.
The kingdom's announcement that Khashoggi died in a "fistfight" was met with international skepticism and allegations of a cover-up to absolve the 33-year-old crown prince of direct responsibility.
On the day of Khashoggi's disappearance, 15 other Saudis, including several officials, arrived in Istanbul on two planes and visited the consulate while he was still inside, according to Turkish police sources. The 15 Saudis knew Khashoggi would enter the consulate to get a document he needed to get married, and once he was inside, the Saudis accosted Khashoggi, cut off his fingers, killed and dismembered the 59-year-old writer, according to media reports. All of the identified individuals have since left Turkey.
Surveillance video showed the man in Khashoggi's dress shirt, suit jacket and pants, although he wore a different pair of shoes. A Turkish official describED the man as a "body double" and a member of the Saudi team sent to Istanbul to target the writer. The man walks out of the consulate via its back exit with an accomplice, then takes a taxi to Istanbul's famed Blue Mosque, where he goes to a public bathroom, changes back out of the clothes and leaves. He later eats dinner with his accomplice and goes back to a hotel, where footage shows him smiling and laughing.
In the days after Khashoggi vanished, Saudi officials initially said he had left the consulate by its back door. Saudi Ambassador to the U.S. Prince Khalid bin Salman, a brother of the crown prince, wrote Oct. 8 that Khashoggi had left, and that claims the kingdom "have detained him or killed him are absolutely false, and baseless."
The fact that the Saudi team would allegedly have a man walking around in Khashoggi's clothes would suggest a premeditated plot to kill the writer.
Last week, a leaked photo apparently taken from surveillance footage showed Maher Abdulaziz Mutreb, a member of Prince Mohammed's entourage seen on trips to the U.S., France and Spain this year, at the consulate, just ahead of Khashoggi's arrival. Mutreb's name also matches that of a first secretary who once served as a diplomat at the Saudi Embassy in London, according to a 2007 list compiled by the British Foreign Office.
By nightfall, Turkish police began searching an underground car parking garage in Istanbul's Sultangazi district. Surveillance footage on TRT showed what Turkish security officials described as suspicious actions, including an image of a man moving a bag from one vehicle to another.
Five Turkish employees of the consulate also gave testimony to prosecutors Monday, Turkish media reported. Istanbul's chief prosecutor had summoned 28 more staff members of the Saudi Consulate, including Turkish citizens and foreign nationals, to give testimony. Some Turkish employees reportedly said they were instructed not to go to work around the time that Khashoggi disappeared.
