BRATTLEBORO, Vt. (AP) — Police in Vermont have accused a man of putting a suspected explosive device at the Brattleboro Retreat psychiatric hospital.

Police later determined the device was a hoax. They arrested 39-year-old Justin Clough, of Brattleboro.

Police and fire investigators met with security officers at the Retreat on Thursday night. The device was found outside of a building on the south side of the campus. Police evacuated the area and a bomb squad and FBI officers were brought in.

Clough was found near the Retreat and arrested. It wasn't immediately known if he had a lawyer and a number listed for him wasn't working.
