Cardi B to show up in court or face arrest

Cardi B Given  Stern Warning in Strip Club Beatdown, Show Up in Court or Face Arrest

Cardi B was just issued a stern warning from the judge in her strip club beatdown case ... show up to court or face getting arrested.

We're told prosecutors expressed their frustration
that Cardi herself was a no-show considering they've already given her a 6-week extension on the case ... so they asked the judge to issue a bench warrant.

The judge denied the immediate request, but did issue a serious warning -- Cardi must appear in court Friday morning -- or there will most likely be a warrant issued.

Cardi's defense team also revealed in court they've been having a tough time getting in touch with her directly -- instead only communicating through Cardi's management team -- and only found out Thursday Cardi had a prior commitment that would prevent her from attending Monday's hearing.

TMZ broke the story ... Cardi is accused of unleashing her posse on 2 strip club bartenders -- Jade and Baddie Gi -- and badly injuring both.
