Bedford man gets 46-month prison sentence for detonating bomb

A man who detonated a bomb under a bridge in Bedford has been sentenced to 46 months in federal prison.

Nicholas Lloyd Nelson, 38, pleaded guilty in June to possession of a destructive device.

In April, investigators say a pedestrian walking his dog narrowly escaped a blast in a drainage culvert along Forest Ridge Drive.

Tipsters and other evidence linked Nelson to the explosion. Prosecutors say he later admitted to blowing up a device under the bridge as well as constructing other bombs in his apartment.
