The wife of Chile's former military ruler Augusto Pinochet has been arrested on charges of tax evasion.
If found guilty, Gen Pinochet's wife faces a jail term
Lucia Hiriart was held with four of the couple's five children.
Their arrests are part of a wider investigation into foreign bank accounts held by Gen Pinochet, who has already been charged with tax fraud.
The courts have stripped Gen Pinochet, 90, of his legal immunity in this case, as well as in a number of human rights cases stemming from his 1973-1990 rule.
Investigating Judge Carlos Cerda ordered the arrest of Pinochet's wife and her four children on charges of filing "maliciously incomplete" tax declarations related to millions of dollars, judicial sources said.
An appeals court is due to decide whether or not to grant them bail later this week.
If found guilty, they all face prison sentences.
Gen Pinochet was charged last November with evading taxes on an estimated $27m he had allegedly hid in foreign accounts.
Gen Pinochet led a 1973 coup and stayed in power for 17 years.
