Nevada Threat Analysis CenterKeeping Nevada Safe

Report suspicious activity

Report behavior, not people. You don't need to be certain, and you don't need to investigate it yourself.

How to report

Use the online form for anything that is not an emergency. It takes about five minutes and no account is needed. If a crime is in progress or anyone is in immediate danger, call 911 instead.

Tell us what you saw, where, and when, and describe the behavior as specifically as you can. Include vehicle descriptions, license plates, physical descriptions, and times if you have them. Photographs help when you have taken them safely and lawfully.

What happens next

Reports are reviewed by analysts at the center, checked against other information, and referred to the agency with jurisdiction when follow-up is warranted. Every report is handled under the privacy and civil liberties protections that govern the center.

Race, ethnicity, religion, and national origin are never a reason to report someone. Reports based on them are not accepted.

Ways to report

Online, any time. In an emergency, call 911.
