Chile judge charges six over ex-president's 1982 death
A Chilean judge has charged six people over the death in 1982 of the country's ex-President, Eduardo Frei Montalva.
The judge said there was now evidence that Mr Frei, a vocal critic of military leader Augusto Pinochet, had been poisoned in hospital.
The arrests come less than a week before Chile's presidential election, in which Mr Frei's son, Eduardo Frei Ruiz-Tagle, is a leading candidate.
The former president's family have long argued he was murdered.
