A man barricaded himself inside a hotel room at Caesars Palace on the Las Vegas strip on Tuesday and was allegedly holding a woman at gunpoint and throwing furniture out of the window, according to police.

SWAT teams from the Las Vegas Metropolitan Police Bureau descended on the hotel room to respond to a domestic disturbance in the around 9:15 a.m. on Tuesday, police said.

Commander Stephen Connell said that it’s not clear if the woman and the man are in a relationship but she appeared to still be unharmed hours into the tense standoff.

“She is still in the room at this time. The female has been heard from and is still OK,” he told KLAS. 

When police arrived at the hotel room, the man refused to open the door and told officers he was armed.

However, according to Connell, police have not yet seen a weapon. He said earlier reports of gunshots appear to be the man throwing items out of the hotel window.

Video footage posted on social media showed someone hurling furniture from a busted hotel room window at the popular resort.

Hotel guest Brooke Cantrell told KLAS that he was swimming in the pool when she saw someone appear to break an upstairs hotel room window and toss a chair through it. 

Police evacuated everyone in the pool area, she said. The rest of the hotel remains open.

“We are aware of the security incident at Caesars Palace,” the hotel said in a statement. “Our team is cooperating fully with law enforcement officers on scene who are handling the investigation. We refer you to the Las Vegas Metro Police Department for more information.”
