Lori Berenson listens to the proceedings March 27, 2001 during her trial in Lima, Peru. Berenson is accused of collaborating with the guerrilla movement M.R.T.A. (Tupac Amaru Revolutionary Movement).
Berenson told reporters she would not be making any immediate statement.
Berenson was paroled in May after serving three-quarters of a 20-year sentence but then was returned to prison in mid-August on a technicality.
The same judge who initially paroled Berenson reinstated her parole Friday.
Berenson cannot leave Peru until her 20-year sentence ends — unless Peru's president commutes it.
