Cardi B Facing Battery Charges Over Mic Toss

Over the weekend rapper Cardi B threw her mic at a concert goer in Las Vegas for throwing water on the stage [click here if you missed that]. 

Now Cardi may be facing charges...

From TMZ 

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.

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.

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.
