Haiti’s former leader Jean-Claude “Baby Doc” Duvalier has been charged with corruption and embezzlement during his 1971-1986 rule, prosecutors say.
Mr Duvalier was allowed to go free after questioning, but a judge will decide whether his case goes to trial.
The ex-leader, who denies wrongdoing, made a surprise return to Haiti on Sunday after 24 years in exile.
He was regarded as a playboy during his time in office, when he used a brutal militia to control the country.
He said he had “come to help” after last year’s devastating earthquake.
Port-au-Prince’s chief prosecutor Aristidas Auguste told Reuters that charges of corruption, theft, misappropriation of funds and other alleged crimes had been brought against him.
