Security officials reopened Boston's federal courthouse building to employees on Wednesday afternoon after an hour-long evacuation tied to a security scare.
A security officer walked out of the courthouse and waved a green flag, signaling that employees could return.
A court official who declined to be identified confirmed by phone that the courthouse was reopened, but only to employees.
Hundreds of people had poured out onto the sidewalks of the city's waterfront district, joining an already large crowd of media which had gathered amid earlier reports that an arrest had been made in the investigation of Monday's Boston Marathon bombing.
Federal and local officials later said those reports were incorrect and no arrests had been made.
The evacuees included courthouse staff, lawyers, attorneys and two cribs with children in them. The courthouse has an in-house daycare center.
