BOSTON — A law enforcement official briefed on the investigation says a suspect in the Boston Marathon bombings is about to be arrested.
The official spoke to The Associated Press on condition of anonymity Wednesday. The official was not authorized to divulge details of the investigation.
The official says the suspect is to be taken into custody by federal marshals and taken to a Boston courthouse.
Law enforcement agencies had earlier pleaded for the public to come forward with photos, videos or any information that might help them solve the twin bombings that killed three people and wounded more than 170 on Monday.
Investigators circulated information about the bombs, which involved kitchen pressure cookers packed with explosives, nails and other lethal shrapnel. But the FBI said nobody had claimed responsibility.
