The FBI in 2011 had interviewed one of the two Chechen-origin Boston bombings suspects, who was killed after a massive manhunt, but apparently let him out of their sights after not detecting any terrorist activity.
Agents in 2011 interviewed Tamerlan Tsarnaev, suspected of being behind the deadly bombings here that claimed three lives and injured over 180, at the request of a foreign government that suspected he might have ties to extremist groups, the FBI said on Friday.
Tamerlan was pronounced dead on Friday morning after suffering shrapnel and bullet wounds in a gunfight with police, while his 19-year-old brother Dzhokhar Tsarnaev, also a suspect, was later arrested in connection with the bombings.
Both the suspects were brothers from a Russian region near Chechnya, which has witnessed deadly bombings carried out by Islamic rebels. PTI
