The government said Tuesday it planned to appeal a decision to release one of the defendants in the Russian spy case on bail. The announcement came from U.S. Attorney Preet Bharara, four days after bail was set for a U.S. citizen charged in the case. A magistrate judge in Manhattan had said the woman, Peruvian-born Vicky Pelaez, could be released on $250,000 bail with electronic monitoring and home detention. The judge said when he set bail that she could not be released before this week because it would take time to set up the bail requirements. An appeal means that a bail hearing will occur before a federal judge, who will decide whether to uphold the findings of the magistrate judge.
