On Wednesday, the disclosure that a bomber was believed to have been seen on the Lord and Taylor surveillance video led to widespread media reports that a suspect was in custody, was under arrest, and was heading to US District Court in South Boston for an initial appearance.
Journalists and spectators converged on the Moakley *federal courthouse, expecting a suspect to be brought in. But top law enforcement officials denied they had anyone in custody, and the courthouse was evacuated after a bomb threat. After a search of the building, employees and visitors were allowed back inside.
They left a few details out of that statement.
