Lori Berenson, a former political activist, is back in the New York after 16 years.

Berenson and her 2-year-old son arrived at Newark Liberty Airport from Lima Peru on Tuesday morning. A Peruvian court granted Berenson approval to visit friends and family in the United States on the condition she returns by January 11.

Berenson was arrested in 1995 by the Peruvian government for aiding leftist rebels. She has served 15 years of a 20 year sentence.
