A federal law enforcement official says the FBI interviewed the older Boston Marathon bombing suspect at the request of a foreign government in 2011 and that nothing derogatory was found.
The official says the FBI shared its information with the foreign government. The official did not say what country made the request about Tamerlan Tsarnaev or why.
The 26-year-old was killed overnight in a shootout with police outside Boston; his younger brother remains at large.
The official spoke on the condition of anonymity because the person was not authorized to speak about the case publicly.
