DENVER (KDVR) — Several schools across Colorado were placed on lockdowns and secure status due to hoax threats on Wednesday morning.

The unconfirmed threats were reported in Boulder, Brighton, Pitkin County, Canon City, Estes Park, Englewood, Glenwood Springs, Alamosa and more.


Around 1:55 p.m., the Littleton Police Department said officers were responding to Littleton High School for reports of an armed person. LPD said the school at 2:15 p.m. that the school was on lockdown. LPD said there were no reports of injuries and no shots were fired.

“LPD is aware of multiple false calls at schools today, however until determined or otherwise LPD is treating this as a legitimate call,” LPD said.

At 3 p.m., LPD told FOX31 there was gunfire in the background of the call. However, the school resource officer did not report hearing any gunfire in the building.

Denver 911 threat

Schools weren’t the only target of the threats on Wednesday. The Denver Police Department said that just after 9 a.m. Wednesday, Denver 911 received a threat by phone involving an FBI Denver facility.

“The threat was unfounded, and it appears, at this time, to be connected to unfounded threats in other jurisdictions. No other Denver locations were the subject of a similar threat,” the Denver Police Department said.

An investigation into the threat is underway.

FBI statement

We reached out to the Federal Bureau of Investigation regarding the threats.

This is the statement they sent us:

“FBI Denver is aware of numerous threats made today to a variety of organizations and institutions across Colorado. The FBI works closely with its law enforcement partners by providing resources and guidance in these investigations and can recommend cases for federal prosecution. While we have no information at this time to indicate a specific and credible threat, we continue to work with our local, state, and federal law enforcement partners to gather, share, and act upon threat information as it comes to our attention.”

It is important to note that law enforcement will use all available resources to investigate a threat until we determine whether it is real or not. Investigating hoax threats drains law enforcement resources and diverts officers from responding to an actual crisis. More information about the consequences of posting hoax threats can be found on We urge the public to remain vigilant, and report any and all suspicious activity and/or individuals to law enforcement immediately.”


The Aurora Police Department said a hoax caller said they planned on coming into Central High School and begin shooting.

Police said the caller played the sound of gunfire in the background of the call.

“The schools perimeter was quickly secured, an SRO was there to assess things before additional officers responded,” APD said.

Everything was cleared at the school before 9 a.m.

Boulder High School

According to the Boulder Valley School District, Boulder High School is under a lockdown due to reports of an active shooter. The Boulder Police Department said the report has been unconfirmed.
