According to the Boston Herald, federal agents have converged on an apartment complex in Revere, Massachusetts -- an oceanside city just to the northeast of Boston -- in order to execute a search warrant. Authorities from various agencies have reportedly descended upon Water's Edge Apartments at 364 Ocean Avenue on the fifth floor.

A law enforcement source tells Fox 25 that a large police presence at a home in Revere is related to the Boston Marathon bombings.
The source said that a suspicious driver was pulled over by Revere police after driving past the State Police barracks a number of times.
The driver reportedly had a "nervous demeanor."
The driver then led police, as well as the FBI, to a home in the area of Ocean Avenue and Beach Street.
It was not immediately known what police were searching for at the home. Three people died and more than 100 were injured after bombs went off within 100 yards of each other near the finish line of the Boston Marathon Monday.
