Special Counsel prosecutors will summon the couple next Monday at the earliest, court sources said yesterday.

Depending on how the questioning goes, one court source said, the younger Chens may be detained. Prosecutors have to request permission to detain them from a Taipei district court judge.

They were suspected of remitting a slush fund totaling at least NT$400 million (US$13 million) to foreign banks, including Credit Suise.

If they were ordered to be detained, the Special Counsel prosecutors would close in on the ex-president, court sources said. “The young Chens are the last two dominoes to fall,” one of them pointed out.
