Court records show the 3 robbery charges Charlo was hit with following an alleged altercation at a San Antonio bar last year were dismissed on Monday. The records list the reasoning as "insufficient evidence."

It's a big deal for Charlo ... who was accused of being a complete jerk to a waitress the day before his brother, Jermell Charlo, fought Brian Castaño in San Antonio last July.

Police, in an incident report, said Jermall was with a big group when the waitress came over with the bill. Cops say Jermall handed over his credit card and ID, but said the card was declined despite multiple attempts to run it.

Officers said in the docs Jermall eventually became upset over it all and took two bill collection binders from the waitress, nabbing everything from the inside of them.

Jermall was eventually arrested ... though his attorney, Kent A Schaffer, tells us he believes video and witnesses from the bar ultimately proved Jermall never did anything wrong.

"Police eventually turned over the surveillance tapes that showed everything that our witnesses said was true," Schaffer tells us. "Jermall never robbed anyone at this nightclub and never used force or threat of force against anyone. We have been saying this the whole time he did nothing wrong."

"We presented the evidence to the ADA who came to the same conclusion -- the surveillance video was a huge part of getting the case dismissed. And the 6 witnesses were also a key factor."

Schaffer continued, "Jermall is ecstatic and training for his next fight -- this is something that has been hanging over his head since August -- he can now get back to fighting instead of worrying about going to trial for something he didn't do."
