Bruce Beck, a 45-year-old Plainville man, allegedly came to work and picked up a green duffel bag containing what appeared to be a live Claymore mine. Police say Beck, who worked in maintenance, had been having problems with coworkers and was involved in an argument on Tuesday.

Police say that Beck pointed the Claymore mine at a victim and held up a trigger device. The Claymore mind was ultimately determined to be inert and not functional.

Police say they found additional military-type equipment in the green duffel bag.

Beck served four years on active duty and 16 years in the reserves. Police say they found a second inert Claymore mine during a search of his home Wednesday night.

Beck was charged with assault by means of a dangerous weapon, possession of hoax device and receiving stolen property.

Beck is expected to be arraigned on Thursday.
