Puerto Rico ? A Puerto Rican militant suspected in a 1983 Connecticut robbery – among the country’s largest cash heists at the time – was arrested Thursday in the U.S. territory, where he lived quietly under an assumed name, the FBI said.

Avelino Gonzalez Claudio, 65, an alleged member of a Puerto Rican independence group, Los Macheteros, was captured while driving in the northern town of Manati, said Luis Fraticelli, the FBI special agent in charge of Puerto Rico.

Gonzalez was among more than a dozen people indicted in the Sept. 12, 1983, robbery of about $7 million from a Wells Fargo armored car depot in West Hartford, Conn.

Fraticelli declined to say what led to the arrest or if authorities had any leads on the two remaining fugitives: Norberto Gonzalez Claudio, a brother of Avelino Gonzalez Claudio, and Victor Gerena, the robbery’s alleged mastermind believed to be in Cuba.
