SOUTH POINT — The investigation continues into a bomb scare that put a South Point neighborhood into voluntary evacuation in the early morning hours of Thursday.

At 1:20 a.m. a man called the Lawrence County 911 Dispatch Center to report there was a bomb behind the Engines Inc. building in The Point industrial park in South Point, according to a release from Sheriff Jeff Lawless.

Responding were the sheriff’s office, the county EMS, fire departments from South Point, Perry Township and Burlington, the Ohio State Highway Patrol and the county EMA.

Because of the early hours the business was already closed, but the residents of the houses nearby were placed on voluntary evacuation. Also parts of County Road 1 were closed.

Investigators traced the call back to a pay phone at a nearby business. There was no one there at the time.

“The phone was taken as evidence and will be fingerprinted,” according to the release. “Detectives will review video tape of the business and another nearby business in the hopes that the caller was captured on surveillance film.”

By 7 a.m. the area was re-opened after the bomb sniffing K-9 unit from Franklin County did not discover any incendiary device.

Lawless is asking anyone with information about the threat to contact his office.
