REVERE, Mass. (MyFoxBoston.com) – Police were seen carrying several large bags from a suburban Boston apartment that authorities say was searched in connection to the Boston Marathon bombing.
The bags were removed from the apartment on Ocean Avenue in Revere just north of Boston at about 2 a.m. Tuesday.
Police did not disclose what was in them and calls to federal and state authorities were not immediately returned.
Massachusetts State Police confirmed that a search warrant was served Monday night but provided no further details.
The Revere Fire Department wrote on its Facebook page that firefighters responded to the scene for a search for "a person of interest."
The FBI is leading the investigation into the explosions, which killed three people and injured more than 170 people.
Heavily armed state troopers, National Guard members and SWAT teams are patrolling the city. Expect bags to be randomly searched on the MBTA.
Gov. Deval Patrick said the area will pretty much stay in lockdown mode. Workers and visitors will not be allowed into that zone, and residents will not be allowed into their homes in the blast zone until further notice.
