DEVELOPING: Three additional suspects were taken into custody in the Boston Marathon bombing, the Boston Police Department told FoxNews.com. Police would not confirm when the suspects were taken into custody, and referred further questions to the FBI. Charges against the new suspects involve providing some sort of assistance to the two main suspects, sources told Fox News. Police did not confirm the gender of the suspects and did not say when or where they were taken into custody. More information was expected to be provided by the US Attorney's office later Wednesday.
