CNN — There 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.
However, there have been no arrests in the Boston Marathon bombing investigation, according to Boston police and the Justice Department.
But two senior administration officials and another federal official then told Townsend that there had been a misunderstanding among officials and that no one has been arrested.
Two Justice Department officials also told CNN's Joe Johns that there has been no arrest, and that authorities were looking into where the earlier confusion came from.
