A US judge granted bail to one person accused of spying for Russia and denied bail to two others after a prosecutor warned the defendants had plenty of helpers in the US to help them flee.
Magistrate Judge Ronald Ellis ruled after 90 minutes of arguments at a bail hearing in New York.
The magistrate said Vicky Pelaez, a Spanish-language journalist who lives in Yonkers, New York, could be freed on 250,000 US dollar (£16,500) bail plus house arrest as soon as Tuesday.
Mr Ellis denied bail to Richard and Cynthia Murphy of Montclair, New Jersey. A bail hearing was postponed for Juan Lazaro, Pelaez' husband.
Prosecutors said earlier that Lazaro told authorities that Juan Lazaro is not his true name and that he passed letters to Russian intelligence.
