BOSTON — Boston police say three more suspects have been taken into custody in the marathon bombings.

In a tweet Wednesday morning, the police department says only that three more suspects are in custody and more details will follow. Police spokeswoman Cheryl Fiandaca confirmed the tweet but 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 U.S. They are accused of using a weapon of mass destruction.
