Georgia Gwinnett College was placed under a “soft lockdown” due to a “violent threat” posed by suspects in a nearby robbery for about 30 minutes Wednesday afternoon.

A robbery occurred at the Home Depot on Lawrenceville Suwanee Road Wednesday afternoon and two armed suspects are at large, according to Gwinnett County police. Because the Home Depot is less than two miles from the college, a lockdown was put in place, spokeswoman Asia Hauter said.

Two victims in the Home Depot robbery were assaulted by the suspects, but no shots were fired, according to Gwinnett County police. Descriptions of the suspects were not immediately available.

The lockdown was lifted after campus police searched all buildings and parking lots on campus and did not find either suspect, the school said in a tweet. Normal class schedules were resumed by 3:30 p.m.

This comes less than a week after an academic building was evacuated due to a student accidentally testing pepper spray indoors. Nobody was hurt in that incident.
