Cops: Mass. house was wired to explode at flip of a light switch

MILTON, Mass. - Police say someone carefully placed an explosive device in a house in Milton, Mass. that was designed to ignite when a light switch was turned on.

A Boston bomb squad disarmed the device Tuesday afternoon. No one was hurt.

CBS Boston reports the homeowner and an electrician came across the device on Tuesday and called police.

The home was vacant at the time the explosive was discovered as it was about to go up for sale. The tenants reportedly moved out on Sunday.

Lindell Williams, the homeowner, told the station the device was discovered in an upstairs bedroom closet.

According to Milton Police Chief Richard Wells, the device was wired throughout the house and was rigged so that if someone flipped the light switch on where it ended, the device would have exploded.

The device was reportedly in a gallon container and was hidden behind a recently plastered section of wall.

Williams, the homeowner, told CBS Boston he believes the former tenants, who are also suspected of pouring concrete down his drains, might be responsible.

Police confirmed they had recently been called to the house for a vandalism report.

Investigators have not commented on a motive in the case and no arrests have been made.
