The alleged incident occurred in 2009.
The Killers have responded to allegations of crew sexual misconduct while they were on tour.
The band said they will be conducting an investigation into their current and former staff following allegations from a female sound engineer that a woman was abused backstage by members of the crew.
The engineer, who shared her account of the alleged event on Twitter, said that she heard crew members “swapping stories” about the woman. None of the band members were implicated in the assault.
A legal representative for The Killers told BBC News that the band are “outraged and appalled” by the allegations and that they have launched an investigation into their former and current employees.
“First and foremost, any allegations of inappropriate behaviour by anyone on The Killers touring team are taken extremely seriously by the band and their management,” they said.
“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.
“The band are astonished and shocked by these claims. The behaviour attributed to them and their crew is unrecognisable and in direct opposition to the principles with which they run their workplace.”
