Prosecutors have found the diary of a woman who has been arrested on charges of aiding the escape of Yoo Byung-eon, the fugitive de facto owner of ferry operator Chonghaejin Marine.
The diary contains detailed information about Yoo's movements since he went on the run.
The woman, identified only by her surname Shin, is in her 30s and was carrying W8 million in cash, as well as five mobile phones and a gadget to detect eavesdropping devices (US$1=W1,021).
Shin is a U.S. citizen and has been working in a compound owned by a cult led by Yoo for the last five years.
Prosecutors believe Shin kept in close contact with followers of Yoo's sect and funded his escape. Another woman in her 60s was arrested on Wednesday for aiding Yoo's escape.
Meanwhile, prosecutors have begun to freeze the assets of Yoo's family, estimated at hundreds of billions of won, to finance the compensation of the hundreds of victims of the April 16 ferry disaster.
Prosecutors said they filed a request to freeze W240 billion of the Yoo family's assets, which amounts to the total sum the fugitive owner and his children have been charged with embezzling.
The assets break down to W129.1 billion owned by the fugitive owner, W49.2 billion from his eldest daughter Sum-na, who was arrested earlier this week in France, W5.6 billion belonging to his eldest son Dae-gyun and W55.9 billion owned by his son Hyuk-ki.
