GULFPORT, Miss.--The Mississippi Gulf Coast was the epicenter of 29 bomb threats called in to courthouses Wednesday. The calls caused evacuations and now extensive investigations. The Miss. Office of Homeland Security sent us a statement saying the calls are similar to ones in Nebraska, Oregon, Tennessee and Washington last month.

Jay Ledbetter, with Homeland Security, said the calls appear to be robotic, with scripted messages, but officials still take the threats seriously. MEMA is also monitoring the threats.

"The Mississippi Office of Homeland Security along with the Jackson Division of the FBI is currently working this issue,”  he said. "If your courthouse receives one of these bomb threats, take all required precautions and notify the FBI, MEMA or the Fusion center, as soon as possible to inform them of your threat.”

He gave us some numbers for you to call if you have any information on who might be responsible- the Mississippi Fusion Center at (601) 933-7200 or the Jackson FBI office at (601)948-5000.

Ledbetter said we get about 400 bomb threats per year in the state. He said each one must be taken seriously and residents should evacuate and follow instructions until the coast is clear.
