A Southington man has pleaded not guilty to making a threat that shut down some libraries in Trumbull County last week.

Twenty-six-year-old Nathan Furlong was arrested Friday on one count of making a terroristic threat and spent the weekend in the Trumbull County Jail.

Police believe Furlong was the person who phoned in a threat last Tuesday, resulting in the shutdown of the Warren-Trumbull County Public Library system and some branches on part of Tuesday and Wednesday.

The bookmobile service was also halted due to the threat.

The bond for Furlong was set at $7,500.  Another court hearing is scheduled for Thursday.
