Cardi B Suspect for Battery After Vegas Microphone Toss

The woman who reported the incident to cops was standing next to the drink thrower — but she claims the mic hit her too. Some video angles seem to show the mic hitting her after it ricocheted off the other fan.

Cardi B might not get away scot-free with that microphone toss in Las Vegas — she’s now listed as the suspect in a battery … TMZ has learned.

The woman who was struck by Cardi’s mic when she hurled it into the crowd at Drai’s Nightclub on Saturday … went to Las Vegas Metro PD the next day to report the incident.

She told police she’d been struck by an item — the microphone — thrown from the stage. Of course, the whole incident was captured on cameras during Cardi’s show.

As we reported, a woman in the crowd threw some kinda liquid at Cardi while she was performing … and the rapper snapped, immediately throwing the mic in retaliation.

The mic struck the drink thrower, but ricocheted and also hit another woman standing next to her … as seen in the footage.

Prior to the altercation, Cardi and her DJ had implored the crowd to splash water on her to cool her off in the triple-digit weather — but obviously, she didn’t take kindly to whatever the woman threw later in the show.

We’ve reached out to Cardi’s camp, but no word back yet.
