By Radu Marinas BUCHAREST (Reuters) – Romanian hacker Guccifer, famous for breaking into emails of former U.S. president George W. Bushs family and entertainment figures, appealed against his arrest on Friday but the chances for his release appeared slim. A source in the prosecutors office confirmed that masked police had netted Marcel Lazar Lehel, known by the aliases Guccifer and Small Fume, on Wednesday and said he was currently being detained for 29 days in Bucharest pending a criminal investigation. (Guccifer) was assigned a criminal defense lawyer, the prosecutors office source said, adding his appeal against his detention would be considered by the court on Monday or Tuesday. Asked by Reuters whether it had received an extradition request for Guccifer from the United States, Romanias justice ministry said it had no information on the matter.
