According to CNN, an arrest has been made in the Boston bombings investigation based on
two videos showing images of the suspect, a federal law enforcement
source told CNN’s Fran Townsend.
The suspect was to be taken into custody by federal marshals
and taken to a Boston courthouse, AP is reporting.

Several media outlets reported
that a suspect had been identified from surveillance video taken at a
Lord & Taylor store between the two bomb blasts.
An official news briefing was scheduled later today.
