Former President Ertha Pascal-Trouillot, who led an 11-month interim government, says she has been released from house arrest but is barred from leaving Haiti pending a coup attempt investigation.

Pascal-Trouillot also said Tuesday that she was forced at gunpoint to write a letter now being used as a key piece of evidence against her."This is terrible injustice for me and for Haiti, in social, human and political terms," Pascal-Trouillot said in a rare interview at her home.

She was arrested Thursday on charges of complicity in the Jan. 6, foiled coup attempt by hard-line supporters of the ousted Duvalier dictatorship. The attempt came after leftist priest Jean-Bertrand Aristide was elected president.

There was no immediate comment from the government, which has not described the allegations in detail.
