WASHINGTON (AP) -- The FBI is taking charge in the criminal investigation of the explosions at the Boston Marathon.
The announcement came Monday night at a news conference in Boston whose participants included Richard DesLauriers, the agent in charge of the FBI in Boston.
Also on Monday night, the FBI said it had set up a phone line for members of the public to call with information about the explosions to contact the law enforcement agency. The call-in number is 1-800-CALL-FBI (1-800-225-5324), prompt (hash)3.
"No piece of information or detail is too small," the FBI said in urging the public to respond.
