A federal courthouse in Boston has been evacuated amid conflicting reports that a suspect in the Boston Marathon bombing is in custody.
The U.S. Marshals Service in Washington says the courthouse was evacuated due to a bomb threat. Spokeswoman Nikki Credic-Barrett says authorities are conducting a security sweep.
Attorney Francis DiMento says he was in a hearing when someone came over the loudspeaker and told everyone to get out in a hurry.
Crowds of reporters are gathered outside. The FBI and the U.S. attorney's office in Boston say no arrests have been made in the marathon bombing.
The courthouse has a day care attached and at least one crib was wheeled out.
