An administrative building at Capital University was evacuated Thursday afternoon after a bomb threat was received and multiple businesses throughout Franklin County also received threats.

Yochum Hall, located on the Mound Street plaza on the Bexley campus, was evacuated shortly before 2 p.m. following a bomb threat, according to information on the university’s social media accounts.

University spokeswoman Nichole Johnson said law enforcement officials had given the all clear around 3 p.m. and staff members were being allowed to return to the building.

Yochum Hall was the only building impacted, Johnson said. Classes at the university ended on Dec. 6, so most students are no longer on campus, she added.

The university remained open and operational throughout the scare.

Lt. Brent Mull with the Columbus police homeland security unit said at least four reports have been made to businesses within the city that are similar in nature.

Mull said all the threats appear to be following a pattern of being emailed or called into the business with a monetary demand.

Columbus police are asking businesses that receive threats to check their location for anything suspicious or out of place. If nothing is out of place, the businesses are being asked to call and make a report with police.

If something is out of place, police are asking the businesses to call back and officers will respond like a bomb threat.

The threats continue to be investigated by Columbus police, state and federal authorities to try and determine where they originated.

Threats have come in across the country to businesses and educational institutions including Niagara University in New York, the University of Washington and Dixie State University in Utah.
