Jean-Claude “Baby Doc” Duvalier was due to attend a hearing in the capital, Port-au Prince, on Thursday afternoon or face arrest.
The ex-leader, who returned to Haiti in 2011 after 25 years in French exile, has already missed two hearings.
He denies all charges, with his lawyers saying the case should be thrown out.
Mr Duvalier’s chief counsel, Reynold Georges, earlier told journalists that the ex-president would not attend Thursday’s hearing. – BBC News
