AKIPRESS.COM - At least 50 people have been killed and another 200 have been injured in a mass shooting at a Las Vegas concert.

A gunman, named as 64-year-old Stephen Paddock, opened fire from the 32nd floor of the Mandalay Bay Hotel toward an open-air music festival.

Police said a suspect identified as a local resident was shot and killed by officers.

They said they were looking for a companion travelling with the suspect as a "person of interest".

Sheriff Joe Lombardo said police believed the shooting was a "lone wolf" style attack, but confirmed they were trying to locate an Asian female named as Marilou Danely.

The shooting happened near the Mandalay Bay Resort and Casino. Video posted online showed the country singer Jason Aldean performing outside the hotel at Route 91 Harvest, a country music festival, interrupted by the sound of automatic gunfire, NYTimes reported.

The music stopped, and concertgoers ducked for cover. “Get down,” one shouted. “Stay down,” screamed another.

Several SWAT teams were sent to the hotel immediately after the first reports of the shooting at 10:08 p.m., and officers reported being pinned down by gunfire, according to emergency radio traffic. Shortly before midnight the Las Vegas Metropolitan Police Department reported that “one suspect is down,” and soon thereafter the police said they did not believe there were any more active gunmen.
