VIDEO - Active shooter drill tests local agencies - Story | LasVegasNow

LAS VEGAS - Las Vegas City Hall was closed for business Friday as first responders teamed up for an active shooter drill.

It seemed like a real crime scene. Police tape blocked off multiple streets. A command post was set-up in front of Las Vegas City Hall, and dozens of police officers and emergency responders from a number of agencies were present.

But, the scene was all a drill intended to train first responders on an active shooter situation.

Media were not allowed inside City Hall during the exercise, because it played out like a real-life scenario.

Police were briefed on the situation. Two active shooters entered City Hall and shot multiple victims. From there, it was up to first responders to react.

Police went in first and engaged in a firefight with the suspects. Additional police and emergency medical technicians followed, once the lobby was secure, to help the victims in the mock shooting.

North Las Vegas Fire Chief Jeff Lytle commended the efforts of the response agencies.

“As a citizen, I'm comforted in knowing that there's training being done to ensure that, when we have this event, that people are trained, that people are skilled, and that they're ready for this event. So, as a citizen, I am thankful that's being done,” he said.

Personnel from Las Vegas, Henderson, North Las Vegas and Clark County participated in the drill. The main purpose is to ensure multiple agencies work together during a mass casualty event.

The training will be reviewed by each department to determine any weaknesses.

Several dignitaries also observed the drill, including U.S. Rep. Dina Titus (Nevada-D), Las Vegas City Councilman Bob Coffin and Las Vegas City Manager Betsy Fretwell.
