Inmate who mailed bomb threat sentenced

An inmate who mailed a bomb threat to a federal agency has been sentenced to 18 months in federal prison.

Glen Sharkany, 42, sent a letter to the Social Security Administration office in Norwalk which contained a diagram of an explosive device that included the words, "I'm going to blow up your office and the IRS office as well," authorities say.

Sharkany was sentenced to 18 months of imprisonment followed by three years of supervised release.

Sharkany is an inmate at the Garner Correction Institution in Newtown. He will begin serving his 18 month federal sentence at the conclusion of his state sentence.
