BOSTON The suspicious devices which forced bomb units to scramble across Boston today were actually magnetic lights that are part of a marketing campaign for a television cartoon.
The reports forced the temporary shutdowns of Interstate 93 out of the city, a key inbound roadway, a bridge between Boston and Cambridge, and a portion of the Charles River but were quickly determined not to be explosive.
"It's a hoax -- and it's not funny," Gov. Deval Patrick said.
All of the devices are magnetic lights which resemble a character on the show "Aqua Teen Hunger Force", on Turner Broadcasting's Cartoon Network.
