Initial reports from CNN’s John King stated that a federal law enforcement source told him that officials have “made a clear identification of a potential suspect” and an arrest had been made.

King originally said the identity of a suspect was determined from video footage taken from a Lord and Taylor store near the second explosion. This and other video footage are being reviewed by investigators.
