BOSTON (AP) -- The FBI and federal attorneys in Boston deny that a suspect has been arrested in the Boston Marathon bombings. Earlier, a law enforcement official, briefed on the investigation, told The Associated Press day that a suspect was in custody.
In a statement, the FBI has asked the media "to exercise caution" and verify information "through official channels" before reporting it.
The blasts killed three people, including an 8-year-old boy. Scores of victims remain in hospitals, many with grievous injuries. Doctors who treated the wounded corroborated reports that the bombs were packed with shrapnel intended to cause mayhem. At least 17, including three young children, are in critical condition.
