Supporters of Puerto Rican independence are welcoming the return of a 69-year-old man who has completed a prison sentence for his role in a 1983 holdup in Connecticut carried out by Puerto Rican militants. It was the largest heist in U.S. history at the time.

Norberto Gonzalez Claudio arrived Thursday in the U.S. territory just hours after he was released from a prison in central Florida. Some 150 supporters raised fists in the air and waved Puerto Rican flags as Gonzalez emerged from the airport.

He pleaded guilty in June 2012 to charges including foreign transportation of stolen money and conspiracy to rob federally insured bank funds.

Gonzalez had eluded the FBI for decades until he was arrested in Puerto Rico in May 2011.
