At 2:10 p.m. today, a report was made of an alleged armed intruder driving through the Butler Community College campus.
"Someone thought they saw someone driving through campus with a gun hanging out the window," said Ryan Entz, executive director of marketing communications at Butler. "We aired on the side of caution and issued a lockdown."
That lockdown remained in place as all of the buildings that were open at the time were searched, which took about 15 minutes, said Marshall Matthews, Butler director of safety and security.
At about 3 p.m. the all clear was given after no sign of the intruder was found in any building or on campus.
Authorities were looking for a 1980s Ford pickup that is cream colored with a red stripe, last seen heading north on Haverhill Road.
The security department did receive information on a person who resembled the subject, but after following up they found that incident, which was about half a mile wast of the college, was unrelated.
"We're extremely fortunate because as you know all college campuses are wide open," Matthews said. "We always have to remain vigilant and prepared."
Matthews said the incident is still under investigation.
