A Southington man is scheduled to appear in Trumbull County Common Pleas Court Tuesday to answer a charge filed after he allegedly made a threat that shut down some libraries in Trumbull County in December.

The Trumbull County Grand Jury on Thursday handed up an indictment charging 26-year-old Nathan Furlong with one count of making terroristic threats.

Police believe Furlong was the person who phoned in a threat on December 12, resulting in the shutdown of the Warren-Trumbull County Public Library system and some branches for two days. The bookmobile service was also halted due to the threat.
