Joint Press Release—Denver Police Department, Colorado Bureau of Investigation, FBI, U.S. Attorney's Office

The Denver Police Department, the Colorado Bureau of Investigation, the Denver Division of the Federal Bureau of Investigation, and the U.S. Attorney’s Office – District of Colorado have joined together to share resources with the public to encourage proactive reporting to law enforcement for situations in which there could be a danger to an individual or the community.

In light of the recent violent attacks in workplaces, stores, schools, and public places, and as pandemic restrictions ease across the nation, we ask you to stay alert. We are not aware of any specific, credible threats at this time, but we ask the public to remain vigilant.

The public plays a critical role in keeping our nation and our neighborhoods safe. If you see something suspicious or notice behavior that does not seem quite right, contact law enforcement. Tell them who and what you saw, where and when you saw it, and why it seemed suspicious or unusual. We recognize that individuals themselves are not suspicious, behaviors are. We will review all reports submitted. Hopefully, the concern turns out to be non-threatening, but your information could save lives. Help us make the community safer. If you see something, say something.

The team of local, state, and federal representatives gathered today provided a variety of resources you may contact to report your concerns, whether they are about someone’s escalating behavior that appears to be heading toward potential violence, or about a concerning motivation or ideological shift that could lead an individual to a dangerous act against another individual, a certain community, or against him or herself. An informed and alert community plays a critical role in keeping our nation safe.
