U.S. agents tracked bin Laden son-in-law for years before arrest

WASHINGTON (Reuters) - U.S. investigators tracked Suleiman Abu Ghaith, a son-in-law of Osama bin Laden, for about 10 years before he was detained in Jordan and brought by the FBI to New York City in the past few days, U.S. officials familiar with the investigation said.

An FBI agent and a New York police detective together spent more than a decade investigating Abu Ghaith, not only for his role as a spokesman for al Qaeda after the September 11, 2001, attacks on New York and Washington but for activities they believed he was involved in before 2001, said one official.
