BOSTON - Two men who authorities say placed electronic advertising devices around the city were released from jail Thursday, apparently amused with the publicity stunt that stirred fears of terrorism and shut down parts of the city.

BOSTON - In nine cities across the country, blinking electronic signs displaying a profane, boxy-looking cartoon character caused barely a stir.

But in Boston, the signs — some with protruding wires — sent a wave of panic across the city, bringing out bomb squads and prompting officials to shut down highways, bridges and part of the Charles River.
