The wife of former Defense Minister Akis Tsochatzopoulos, Viki Stamati, was remanded in custody on Friday after being charged with money laundering.
She denied before a prosecutor that she had any dealings with the offshore firms her husband is alleged to have used to launder under-the-table payments for arms purchases.
Stamati was taken to Korydallos Prison, where Tsochatzopoulos and his daughter, Areti, were already being held.
Stamati?s brother, Panayiotis, was bailed pending his trial
Ten people who have been implicated in the money-laundering network that prosecutors believe was used by Tsochatzopoulos to conceal millions of euros in under-the-table payments from defense procurement deals are to face an investigating magistrate. They include associates and relatives.
