Auburn University Public Safety and Auburn police received reports Monday evening of clowns on campus.

Auburn police Assistant Chief Will Mathews said Auburn police received several calls Monday night and only one report.

A woman reported seeing two to three people wearing clown masks while walking across campus, he said.

Officers immediately responded and didn't see anyone dressed as a clown, Mathews said.

"There are a lot of cameras around where this was reported and no one was able to see anything," he said. "There was no ominous lurking threat that we know about."

Authorities were also alerted to several social media posts that suggested clowns were roaming the university campus.

It's unclear if the group wearing clown masks was intending to cause mischief or not, but it likely attracted attention due to recent online threats from alleged clowns.

Mathews asks residents and students to be conscious of their surroundings and to consider avoiding doing anything that could cause alarm, including wearing clown costumes for the time being.

The University of Alabama issued an alert saying any rumored threats against the university by alleged crowns aren't credible.

Clown sightings and social media threats from "clowns" threatening to shoot up schools have circulated across Alabama in recent days.

Most of the threats, however, turned out to be pranks.

Few acts of violence (or mischief) by individuals dressed as clowns have been reported and verified.

Someone dressed as a clown allegedly chased two young teens in Brighton on Sunday night. An 18-year-old was arrested in West Blocton on Monday and accused of jumping in front of a car while wearing a clown mask.

Auburn police will continue to patrol campus and investigate any suspicious activity, Mathews said.

There were also reports that students are searching the campus for people dressed as clowns.

"For your safety, we strongly encourage you to leave this job to Auburn police," Auburn University Public Safety stated in a notice. "Please use good judgment and avoid wearing clown masks, as it could be perceived as a hazard or threat to others."

Anyone wishing to report suspicious activity is asked to call 911 or Auburn Police Division's non-emergency number at 334-501-3100.
