12:39AM Update: Originally Boston Police reported having 4 individuals in custody, they have now backed off that. Local, State and Secret Service plus helicopters are now searching the surrounding area with high powered lights. They don't know if it is real or a diversion. Supposedly 2 individuals reported seeing between 2-4 parachutists land in the "hard zone" surrounding the Fleet Center.
What's weird is that no other news organizations are reporting it as of yet.
