LAS VEGAS - Cardi B will not face criminal charges over an incident in which she threw her microphone at a member of her audience, police in Las Vegas said.
Detectives launched a battery probe into the "WAP" star's actions after she retaliated when a concert-goer chucked a liquid at her.
Footage posted on social media shows the "Money" singer recoiling after someone close to the stage splashed the contents of a cup in her direction.
In the clips, Cardi B can be seen pausing briefly, before flinging the microphone back in the same direction.
However, some videos online appear to show the mic making contact with a different member of the audience.
Las Vegas Metropolitan Police Department said that a woman had contacted them to report a battery, and that they had begun an investigation.
But on Thursday, they confirmed that the probe had been dropped.
"After a thorough review of this case and with the consultation from the Clark County District Attorney’s Office, this case has been closed as having insufficient evidence," a statement said.
"No charges will be filed in relation to this case."
