Boris Volfman was arrested at Istanbul's Ataturk airport on suspicion of organ trafficking and fraud after flying from Bangkok on Friday night, Turkey's Dogan news agency reported.
The Ukrainian-born Israeli citizen reportedly came to Turkey to harvest organs from desperate Syrian refugees, the daily Vatan newspaper reported.
A court on Saturday ordered his extradition to Israel after a 40-day arrest period.
There was no comment from Turkish or Israeli authorities concerning Volfman's arrest.
Turkish media reported an investigation has been launched to determine his contacts in Turkey.
Local media outlets reported Boris' last name as both Volfman and Walker.
