Four people involved in a complex securities fraud scheme tied to the computer hackings of JPMorgan Chase and other financial institutions were arrested in Florida and Israel, Bloomberg reported on Tuesday.

JPMorgan said last October that names, addresses, phone numbers and email addresses of about 83 million customers were exposed in a hacking attack, making it one of the biggest data breaches in history.

Israeli police spokesman Micky Rosenfeld said he did not have details of a scam involving JP Morgan but confirmed three arrests.

"Three Israeli citizens were arrested on Thursday and have been remanded in custody, appearing in court in Rishon Lezion, near Tel Aviv," Rosenfeld told Reuters.

Bloomberg's report added that a fifth person remains at large, citing officials.

"As alleged, the defendants manipulated trading in U.S. securities from overseas, using fake identities to funnel millions of dollars in unlawful proceeds through a web of international shell companies," Manhattan U.S. Attorney Preet Bharara, said in a statement after a grand jury indictment was unsealed.

"Using false and misleading spam emails sent to millions of people, these defendants allegedly directed their pump-and-dump scheme from their computers halfway around the world."

The indictment named three defendants: Gery Shalon, Joshua Samuel Aaron and Ziv Orenstein.
