Three more suspects have been arrested in the Boston marathon bombings investigation.
Police said only the three more are in custody and more details will follow. They referred all other questions to the FBI.
Three people were killed and more than 260 injured on April 15 when two bombs exploded near the finish line.
Suspect Tamerlan Tsarnaev died after a gunfight with police several days later. His brother, Dzhokhar Tsarnaev, was captured and lies in a hospital prison.
Both are Russian natives who lived for several years in the US.
