Possible suspect in Boston marathon bombing identified

Boston police and the FBI are trying to solve the puzzle of the Boston bombing which happened Tuesday morning. Authorities want to question a man seen on the surveillance video regarding his possible relation to the incident.

The sources identified the man to be wearing a white baseball cap worn backwards, a light-colored hooded sweatshirt and a jacket. News of this possible suspect was said to be of "significant progress" in the case but no arrests were made as of today.

Sources said that the suspect is already in custody, but both the Boston police and FBI denies this, assuring that no arrests had been made with regards to the bombing.

"We got him," but wouldn't clarify whether that meant a suspect has been identified or arrested", a Boston law enforcement source said. And some federal sources also agree that it is too early to say investigators had identified the suspect. However, several other sources told that they already have a clear identification.

The U.S. government has warned federal agencies in the past that terrorists could turn pressure cookers into bombs by packing them with explosives and shrapnel and detonating them with blasting caps.
