An Horry County grand jury indicted a Murrells Inlet man on a charge of making a bomb threat to St. James High School in August, according to indictments released Monday.

Tony Franks, 53, of Murrells Inlet was indicted on a charge of threatening use of a destructive device, according to court records.

Franks was arrested Aug. 23, the day of the threat, and later released on Oct. 3 on $15,000 bail, according to records at J. Reuben Long Detention Center.

Horry County police were called to the school that morning and evacuated students after school authorities received an anonymous threat, officials said. The caller told school officials at 8:38 a.m. that a bomb would go off within 30 minutes.

Students were evacuated while the Horry County police department State Law Enforcement Division bomb squad and K-9 unit checked the school.

Two hours later the school was cleared and students reentered the building, police said.

The violent crimes section of Horry County police investigation led police to a home on Jay Street where Franks was found and the phone used to make the threat was recovered.

“The Horry County Police Department will not tolerate the continued practice of bomb threats being called into and written at our schools,” Sgt. Robert Kegler said at the time of the incident. “We will continue to utilize our resources as needed to investigate these incidents along with identifying and arresting any suspects found to be responsible.”
