"Juan Lazaro", one of the suspects in an alleged Russian spy ring, has admitted that he worked for Russia's intelligence service, according to a bail letter provided by the United States Attorney's office in the Southern District of New York.

The document states Lazaro made a "lengthy post-arrest statement on June 27th," after he waived his Miranda rights, in which he allegedly told federal agents that he was not born in Uruguay, that "Juan Lazaro" is not his real name, that his house in Yonkers had been "paid for by the 'Service' and although he loved his son, he would not violate his loyalty to the 'Service' even for his son."

The document also says "Lazaro," who is married to co-defendant Vicky Pelaez, told agents she delivered letters to the "Service" on his behalf, and that he refused to provide his real name to prosecutors.

"Lazaro" is currently appearing at a detention hearing in a New York Federal Courtroom to determine whether he qualifies for bail.
