Police swarmed on one of Las Vegas's most famous casinos after reports of an "active shooter" there.
The Bellagio Resort and Casino in Las Vegas was locked down briefly and guests poured into the surrounding streets following reports of a burglary and possible active shooter.
Tyler Perkins said he was stood outside the complex when "hundreds start pouring out the door". Large police forces arrived at the scene and it remains unclear whether anyone was injured.
Early reports on social media of shots being fired at the busy casino and hotel were false and there were no injuries, the Las Vegas Police Department said on Twitter. South resort about 12:50 a.m., Metropolitan Police Department Lt. Michael Rodriguez said.
The Bellagio was on lockdown after the incident for about 30 minutes, ABC News reported, with certain areas of the hotel closed off to patrons.
A witness said she saw an armed burglar wearing a pig mask near a Rolex store.
Guests and tourists were pictured fleeing the hotel while others reportedly hid under tables during the incident which took place at around 1am local time (8am GMT).
