No Suspect Arrested in Marathon Bombing

Amid conflicting reports, officials have clarified that no arrest has been made in connection to Monday's twin bombing in downtown Boston.

"Despite reports to the contrary there has not been an arrest in the Marathon attack," said the official Twitter account of the Boston Police Department, @Boston_Police.

The FBI and U.S. Attorney in Boston also said reports of an arrest were untrue.

News organizations including CNN had earlier reported that an arrest had been made in connection to the bombing but appeared to back away from the initial report of an arrest.

The Assocated Press had reported that a suspect was taken into custody and would appear in federal court in Boston.

Reports even stated that a surveillance video from a Lord & Taylor department store was used to pin down a suspect's identity, according to an official who spoke on the condition of anonymity to the Associated Press.

An aggressive investigation continued Wednesday by law enforcement agencies following Monday's bombing that killed three people and injured more than 170.

Images of investigators clad in white jumpsuits, scouring the two bombing sites in downtown Boston in search of clues, have circulated among the media.

Investigators have solicited members of the public to forward any photographs, video or tips regarding the bombings, and the FBI has released information regarding the bombs crafted from pressure cookers stuffed with nails and explosives.

A news briefing on the status of the bombing investigation is scheduled for 5 p.m. Eastern Standard Time.
