In a scene that could have come straight from off the latest blockbuster, Vegas became its own movie set as police SWAT blasted through a 20th floor window and held a stand-off for 6 hours with a man from Room 2036. Rumours had it they had also rappelled down the outside of Harrahs casino - but they've since been denied.

The gunman had shot and killed a man in the early hours of the morning as 3 floors of hotel guests were evacuated still in their night clothes

The gunman shot into the hallway as police and paramedics arrived during the initial hectic minutes, Jones said. The victim was pronounced dead later at a hospital.

The suspected gunman also shot out of the room as SWAT officers got in place for the standoff and assault, Jones said, adding there were clear signs of a struggle between the gunman and the man who died after the original shooting.

Neither gunman or the victim have been identified.

However, the good news in all this. All is ok at Harrahs - the casino remained open the entire time
