"This person's story is appalling and, while The Killers do not have the same touring crew in 2020 that they had earlier in their career, they will be conducting a thorough investigation into past and present tour staff.
"Their legal team will be reaching out to this person for more information and clarity on the alleged incidents as detailed, as well as to the audio vendor who provided crew for the tour."
It went on to say that the band were "astonished and shocked" by the claims.
"The behaviour attributed to them and their crew is unrecognisable and in direct opposition to the principles with which they run their workplace."
A Twitter user going by Chez Cherrie had posted a blog several years ago detailing her time working for an unnamed band, saying she was the only woman on the crew.
On Tuesday she reposted the blog on Twitter and revealed the band was The Killers.
She described an incident in Milwaukee, saying: "We were about halfway through our load-in when the FOH [front of house] engineer came over radio and said, 'Hey guys, there is a girl set up in Dressing Room A. Put your name on the list outside the door with your radio channel and we'll call you when it's your turn.'
"I continued my load out, occasionally hearing a name come over the radio to notify them that it was their turn on the train in Dressing Room A."
The sound engineer alleged that crew members would "swap stories" about the incident and claimed she saw a security guard ask whether anyone was going to check on the woman in the dressing room.
"The security guy said, and I will never forget this moment because a piece of me died that night, 'That girl in Dressing Room A is passed out and naked. Is anyone going to take care of her? Do you have a number of a friend or someone we can call?'"
She claimed the men on the bus laughed it off.
She concluded that her "heart hurts" for the unnamed girl.
"I cried that night in my bunk. I should've left the tour. I should've spoken up for that woman. I should've defended her.
"I should've gotten off the bus that night and picked her up off the bathroom floor, found her panties and made sure she was okay. I should've known her name. I should've done something. I should have said something."
