Former four division world champion Adrien Broner was officially indicted Thursday on assault and robbery charges, the next step in prosecutors' case against the the boxer known as 'The Problem.'

The charges arise from a lawsuit filed by a man who accuses Broner of pointing a handgun at him during a dispute over high stakes gambling at a Cincinnati bowling alley in January.

The man alleges that he won thousands of dollars from Broner, but the fighter waited for him outside of the bowling alley with the weapon and then proceeded to knock him unconscious and rob him.

Broner was indicted on an aggravated robbery charge, a first-degree felony that carries a maximum sentence of three to 10 years. He also was indicted on second-degree charges of felonious assault and robbery, which carry sentences of two to eight years. Bond was set at $100,000. No date has been set for a pretrial hearing.

Earlier this week, the 26-year-old boxer was jailed in Cincinnati for violating probation in an unrelated reckless driving case. He was ordered to spend 10 days in jail.

Broner was last in the ring on April 1, when he retained his title with a ninth round stoppage of British fighter Ashley Theophane, who is promoted by Floyd Mayweather Jr.
