RIPLEY, W.Va. (WSAZ) -- Deputies in Jackson County, W.Va., are searching for the person who demanded money from a bank over the phone and threatened to blow up two buildings.

The call came in to the BB&T in Ripley at about 9:05 a.m. Friday.

Sheriff Mike Bright tells WSAZ.com that the caller told the bank employee that they needed to drop $50,000 in a blue car parked behind the bank within 15 minutes, or he would use a cell phone to activate bombs at both the bank and Ripley Elementary School.

Instead, the worker at BB&T called 911, despite a warning from the suspect to not call for help, and police responded to both the bank and the school. Both buildings were immediately evacuated.

After 15 minutes, no bombs exploded. There was also no blue car in the bank parking lot.

Bright says a bomb team from the Kanawha County Sheriff's Department and one from the West Virginia State Police helped search for any explosives. The FBI even joined the investigation. They didn't find anything.

Everything was back to normal by 11 a.m., according to Bright, but the person behind the threat is still on the run. Investigators are trying to trace the phone call to bank.

Bright believes the suspect may have some connection between the bank and the school since both buildings are several miles apart and there are other banks and schools in the area.

Shortly after the call came in, Bright says he notified other banks in town in the event the suspect was trying to get all of the police in one location and rob a different bank. During this time, some banks in the area locked their doors.

Bright says the school did a great job handling the situation and getting the kids to safety. More than 700 students at Ripley Elementary School evacuated the building within four minutes. They were moved to the high school gym while the situation was ongoing.

If anyone has any information about the threat, they're asked to call the Jackson County Sheriff's Department tipline at (304) 373-2209.
