Chilling police audio released Monday paints the frantic scene in Las Vegas as a lone gunman squeezed off shot after shot into a crowd of thousands of concertgoers.

The harrowing communications between law enforcement officers were obtained by the Blast.

In parts of one recording, responders can be heard calling in reports of gunshot-wound victims — as apparent gunfire pops off in the background.

“We can’t worry about victims!” one officer snaps. “We need to stop the shooter before we have more victims! Anyone have eyes on this shooter?”

Soon after, a dispatcher pleads, “Hey officers, please stay calm! Just relax. We’re trying to get this set up. Just stay calm.”

Another officer reports, “Gunfire — it’s going right over our heads! There’s debris going over our heads!”

Disturbing calls continued to pour in of injured victims.

“Gunshot wounds to the chest and head, I need immediate medical!” one officer yells. Another reported “multiple GSWs [gunshot wounds] to the chest, legs, terminal arteries.”

Someone else warns that responding cops risked being shot at “in plain sight.”

“Every officer that comes up is going to be a target if they’re driving on Las Vegas Boulevard because it’s coming from Mandalay Bay on the boulevard side,” the person advises.

Gunman Stephen Paddock left at least 58 dead and more than 515 injured after opening fire at the crowd at the Route 91 country music festival. He opened fire from a window of a 32nd-floor hotel room at the Mandalay Bay.
