This is the scene as Las Vegas police officers move in on the Mandalay Bay resort where gunman Stephen Paddock was raining bullets down on festival goers from the 32nd floor of the hotel.
The video footage shows the confusion, fear and panic as lives were being lost in what became the deadliest mass shooting in modern US history. At least 59 were killed and more than 500 injured in the incident.
Police can be seen trying to direct people to safety from behind a wall as the sound of gunfire crackles in the background.
Members of the crowd are told to "get down" while sirens can be heard arriving at the scene before being drowned out by more gunfire. Police recovered 47 firearms from Paddock's hotel room and home, including 12 modified semi-automatic weapons which could fire more rapidly at up to 800 rounds per minute.
The rapid speed of fire can be heard in the video as police find protection from behind a wall before moving more people on from the area.
What had been an evening of music and enjoyment quickly turned into something resembling a war zone.
The shooting started at 10.08pm on October 1 and police said it continued for "between 9 and 11 minutes".
Paddock had already taken his own life by the time a Swat team broke down the door to his room at 11.20pm.
