AceShowbiz - New York prosecutors are exploring the possibility of upgrading the charges in Cardi B's strip club attack case by presenting their evidence to a grand jury.

The "Money" hitmaker, real name Belcalis Almanzar, was charged with misdemeanours for assault and reckless endangerment following her arrest in October (18), after reportedly becoming involved in an altercation with a pair of female employees at New York City's Angels Strip Club last August.

She rejected a no jail plea deal to settle the case in April, indicating her plans to fight the allegations at trial, and she returned to Queens Criminal Court for a hearing on Friday, May 31.

Cardi, who wore a bright pink pantsuit for the occasion, remained quiet in court as the judge revealed prosecutors were planning to call in members of a grand jury to hear the case after "further investigation", reports TMZ.

The news is telling as the procedure is typically reserved for serious felonies, although authorities have yet to reveal what they uncovered during their investigation.

Cardi stands accused of brawling with bartender sisters Jade and Baddie Gi amid allegations suggesting Jade once slept with the star's husband, Migos rapper Offset.

They claim the mother-of-one then had members of her entourage assault them by hurling bottles and chairs at the women.

At the time of her arrest, Cardi's lawyer said, "We're aware of no evidence that she caused anybody any harm on that night. We expect that the matter is going to be resolved expeditiously".

Cardi is next due in court on 9 August.
