‘No other devices’ complicates police probe

Officials investigating the Boston Marathon bombing said no additional explosive devices have been discovered other than the two that detonated near the race’s finish line, a development that could complicate the case.

At this point, no one is in custody in connection with the Monday attack that left three dead and sent 176 to area hospitals, Boston Police commissioner Ed Davis said at a press conference. Of the injured, 17 remain in critical condition.

Late on Monday, police searched a Boston area apartment of a Saudi Arabian student who was injured in the blast, law enforcement sources said.
