When the Soviet Union collapsed in December 1991, Hanssen, possibly worried that he could be exposed during the ensuing political upheaval, broke off communications with his handlers for a time. The following year, after the Russian Federation took over the defunct USSR's spy agencies, Hanssen made a risky approach to the GRU, with whom he had not been in contact in ten years. He went in person to the Russian embassy and physically approached a GRU officer in the parking garage. Hanssen, carrying a package of documents, identified himself by his Soviet code name, "Ramon Garcia," and described himself as a "disaffected FBI agent" who was offering his services as a spy. The Russian officer, who evidently did not recognize the code name, drove off. The Russians then filed an official protest with the State Department, believing Hanssen to be a triple agent. Despite having shown his face, disclosed his code name, and revealed his FBI affiliation, Hanssen escaped arrest when the Bureau's investigation into the incident did not advance.
