Overland Park Police Department officers helped search the campus after JCCC police received reports of a suspicious person with a weapon.
At 4:30 p.m., the Kansas college tweeted that police had ordered a full campus lockdown.
"Everyone should remain in a safe place until released by police," the college said.
Greg Mason, spokesman for Overland Park Police, says as of 5 p.m., officers have yet to find anything to confirm the reports.
All classes have been canceled for the rest of Thursday.
