Three more suspects have been taken into custody in the marathon bombings, city police said Wednesday.

The police department made the announcement in a tweet Wednesday morning, saying more details would 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.

Tamerlan Tsarnaev's relatives will claim his body now that his wife has agreed to release it, an uncle said. Tsarnaev, 26, has been at the medical examiner's office in Massachusetts since he died after a gunfight with authorities more than a week ago.

Amato DeLuca, the Rhode Island attorney for his widow, Katherine Russell, said Tuesday that his client had just learned that the medical examiner was ready to release Tsarnaev's body and that she wants it released to his side of the family.
