(NBC NEWS) Investigators in two Massachusetts cities were seeking the renters of a house for sale that was intricately wired to explode and cause "significant destruction" if someone had simply flipped a light switch, police said Tuesday night.
The homeowner, his attorney and an electrical inspector were conducting a pre-sale inspection when the electrician discovered the mechanism, Milton Police Chief Richard G. Wells Jr. told reporters Tuesday. Boston police bomb specialists worked in the house, on Craig Street in Milton, for several hours before declaring it disarmed and safe.
"It took some work to put it in there," said Wells, who described the mechanism as involving wires meticulously snaking through several rooms from a gallon container of an incendiary substance, which was "secreted inside the house," to a particular light switch.

"We believe the intention was that if someone had flipped the light switch on where it ended, the device would have exploded," he said.
