Howard Community College was evacuated Thursday morning after someone called in a bomb threat to local police.
Howard County police officials said they ordered all students out of the Columbia school before 10 a.m., after receiving a call stating there was a bomb on the college's property.
After searching the school, police ruled the threat a hoax and allowed students to return to class before 11 a.m., officials said.
Mike Scrivener, a college spokesman, said the buildings were evacuated for about 40 minutes and the disruption was minimal.
"Classes have resumed and the police are still investigating," he said.
