Officials may have learned the name of one of the suspected bomb plotters. Officials tell ABC that after a 24-hour intelligence manhunt, including the analysis of flight logs and other documents, they might have learned the name of one of the men suspected of plotting an attack on New York or Washington D.C. The tip that triggered the manhunt was extremely vague: that two men, one described as 5 feet tall, the other 5-foot-8, were planning an attack in New York or Washington on the anniversary of the September 11 attacks. The source also mentioned a third man, who may have gone to Europe. One of their names might be Suliman, the tipster said. Nevertheless, the source was deemed reliable enough to prompt heightened security in both cities, with police setting up checkpoints and closely monitoring mass transit.
