FBI close in on one of the suspects

The net was last night closing in on at least one individual believed to be responsible for the Boston Marathon bombings which claimed the lives of three people and injured 176 others in the worst attack on US soil since 9/11.

The crowded scene in central Boston during Monday’s marathon was recorded by surveillance cameras and various media outlets there to cover one of the biggest events in the city’s sporting calendar.

That footage provided investigators with significant video of the area before and after the two blasts.
