The detention of Camacho Negron took place on Tuesday after his participation in a progressive activity at Puerto Rico University in the capital sector Rio Piedras.

FBI spokesperson in Puerto Rico Harry Rodriguez confirmed the veteran independence fighter remains jailed in Guaynabo Federal Prison in San Juan.

In an attempt to justify the detention, police authorities alleged that three days after his release, Camacho Negron violated parole regulations in 2004.

The prominent leftwing leader, sentenced for his alleged participation in the theft of 7.3 million dollars against Well Fargo enterprise in Connecticut, US in 1983, has never recognized the federal authorities.

That is why former President William Clinton did not include him among the Puerto Rican political prisoners he pardoned in 1999.
