(NEWS CENTER) -- The Maine State Prison showroom, which sells items made by inmates, was closed Monday for an unlikely reason -- it was burglarized.

Thomaston police said the burglary was reported to police early Monday morning. Police Chief Kevin Haj would not talk about how the showroom was broken into or what was stolen.

All the wood products in the showroom, from furniture to crafts to bird feeders, are made by inmates working in one of Maine's prisons.

The store will remain closed as authorities investigate.

The prison industries program is designed to teach prisoners marketable skills and keep them occupied while serving their time.
