[JURIST] Spanish newspaper El Mundo reported Wednesday that a disk seized from the home of one the suspected Madrid train bombers contained detailed plans of New York's Grand Central Station [El Mundo report in Spanish], including "highly specialized technical information." The disk was confiscated within two weeks of the March attack, but the FBI was not warned about the information until December. Reuters has more. In New York, Mayor Michael Bloomberg said Wednesday that the NYPD has "known about the data on the computer for a long time" and has "taken the appropriate steps... to beef up security at all of the major transportation hubs." A US Embassy official confirmed that Spanish authorities turned over the information on the New York threat in December, but declined to go into further detail. AP has more.
