Khashoggi was killed on October 2 last year. The Saudis dismembered him after killing him but his remains have not yet been found.
Turkish media on Thursday published images of a so-called "local collaborator" who allegedly helped the Saudi hit squad dispose of the body of murdered journalist Jamal Khashoggi, citing Istanbul police.
The dissident journalist and Washington Post contributor was dismembered after being killed on October 2 at the Saudi consulate in Istanbul but his remains have not yet been found.
CCTV images leaked previously showed a Saudi agent leaving the consulate after the murder wearing Khashoggi's clothes, who was identified as a "body double".
At one point, a hooded man was seen walking alongside him, who was identified in an Istanbul police report as a "local collaborator, the private NTV television reported.
After weeks of denial, Saudi Arabia admitted that Khashoggi had been killed after entering the consulate to obtain the paperwork necessary for his upcoming marriage to a Turkish woman called Hatice Cengiz.
Turkey says he was killed by a team of 15 Saudis who strangled him, and Ankara has repeatedly asked Riyadh to identify the local who allegedly helped them dispose of the body.
The police report also said that after the murder, the hit team ordered a large quantity of meat which was then delivered to the Saudi residence near the consulate where there was a large industrial oven.
Several Turkish media outlets speculated whether the oven may have been used to dispose of the dismembered corpse.
"Was barbecuing meat... one of the previously made plans?" wondered the police report, which was published by the state-run Anadolu news agency.
The murder sparked international outrage and hurt the kingdom's image.
Riyadh arrested a number of senior Saudi officials allegedly involved in the murder.
