The Israel Police arrested a man suspected of heading a US-based internet extortion and sex ring.
The man was arrested earlier this week and his computer was seized, police announced on Thursday, at the request of the FBI.
According to suspicions, the organization extorted over 100 young women, most of them from the United States.
The suspect's custody was extended by six days on Tuesday at the Rishon Lezion Magistrate's Court.
Police said they are continuing to take part in an international investigation with American law enforcement agencies.
