In the video, it appears that good Samaritans, who were armed, came to the aid of the officers.

Reno Public Market has activities planned throughout the weekend for grand opening attendees.

Reno Police, Nevada State Police, and the Washoe County Sheriff's Office conducted a Sideshow Enforcement Operation Saturday evening.

The celebrations were designed to change the way students experience mathematics by hosting special events.

Police called it a "swatting" event.

The lockdown was lifted less than one hour later. 

The lockdown happened before 9:30 a.m. and was lifted about an hour later.

Earlier, WCSD closed schools due to poor air quality, so no students are on campus.

Police say a nearby domestic disturbance prompted the initial lockdowns.
