One person was fatally shot inside a Las Vegas hotel room Thursday night, prompting authorities to place the entire building on lockdown.
The shooting occurred inside a hotel room on the eighth floor of the Mirage on the Las Vegas Strip, police said.
Another two people are believed to have been injured in the shooting, according to the local station 8 News, which cited a source with knowledge of the investigation.
The Las Vegas Metropolitan Police Department asked the public to avoid the area as the situation and investigation are still active. The gunman remains at large.
Videos posted to Twitter show a heavy police presence at the hotel and hotel guests said no one is being let into or out of the building as officers go room to room to check on guests. In one video, an officer can be seen carrying a ballistic shield.
