Multiple 911 calls about about an active threat reported at three separate locations prompted CU-Boulder to issue a campus alert Wednesday afternoon.

The alert was issued just hours after a man wielding a machete was shot and killed by police inside of a campus building.

Two of the threats were reported on campus, the other in the UMC, CU-Boulder Police said in a press conference Wednesday afternoon. Police responded to the calls and were able to determine that the threats were unfounded.

It started around 1:25 p.m., when the university tweeted that police officers rushed to the UMC and College Avenue on a false report of an active shooter.

They said the scene was all clear and that nothing was found.

Twenty five minutes later, CU tweeted that there were unconfirmed reports of an active harmer at the UMC.

“Avoid area,” the alert read. “Take appropriate protective action.” A 9NEWS reporter in the area saw people self-evacuating from the UMC.

Shortly after that, CU tweeted that the reports of an active shooter at the UMC are believed to be a hoax.

CU-Boulder Police said the alert was issued as a precaution, and there is no continuing concern for public safety.

Both the Champions Center and the UMC remain closed Wednesday for investigation.
