(CNN) — According to CNNthere is conflicting information as to whether someone has been arrested in connection with the Boston Marathon bombings. A federal law enforcement source told CNN’s Fran Townsend that someone was arrested. But later, two senior administration officials and another federal official told Townsend that there had been a misunderstanding among officials and that no one has been arrested.
Investigators in Washington and Boston denied Wednesday that an arrest had been made in the bombing of the Boston Marathon. They had earlier said there was “substantial” progress in the case.
