*UPDATE: A suspect believed to be Ahmad Khan Rahami, earlier named as a "person of interest" in the New York City and New Jersey bombings, was taken into custody this morning, according to law enforcement sources.
Authorities are urgently searching for a "person of interest" in the New York City explosion, identified as 28-year-old Ahmad Khan Rahami, according to a memo circulated by the NYPD.
