The Monmouth County Courthouse was evacuated early Thursday afternoon.

According to Monmouth County Sheriff's Office Public Information Officer Cynthia Scott a 9-1-1 bomb threat came into the courthouse around 12 p.m. Thursday afternoon. At 12:30 p.m. the courthouse was evacuated and area K-9 explosives-detecting dogs were brought in to sweep the building.

"It takes several hours for the building to be swept," explained Scott. "By the time the sweep would be completed, it would be late in the afternoon so Judge Lawrence Lawson decided to close the building down and send employees home for the day."

Scott explained that during the sweep of the building nothing was found. At this time, the person who made the bomb threat is still unknown. The Monmouth County Sheriff's Office and the Monmouth County Prosecutor's Office are currently investigating.
