A warrant has been issued for the arrest of boxer Adrien Broner on charges of felonious assault and aggravated robbery, according to multiple reports. In an incident that took place in January outside a Cincinnati bowling alley, the WBA super lightweight champion is alleged to have beaten up and robbed at gunpoint a man who had just won large sums of money from him.

TMZ Sports broke the story, which was confirmed by RingTV.com and Boxing Junkie, and reported that it had “obtained official documents” detailing the incident. The alleged victim told police that he and Broner, who was bowling in the lane next to him, engaged in several high-stakes wagers, and when he decided to pocket his winnings and leave, the fighter jumped him outside the alley.

TMZ Sports claimed to be quoting from court documents in reporting that after assaulting the man, Broner “then retrieved a handgun from his vehicle, approached the victim, demanded money, then struck [the victim] in the face with a closed fist a second time, this time causing the victim to be rendered unconscious. … Broner was then observed taking money out of the victim’s pockets while he was unconscious before fleeing the scene.”

A post to Broner’s Instagram account from several days ago claims to show the boxer winning $1,000 with a bowling trick shot.

Broner is a native of Cincinnati and has credited boxing with saving him from a life on the streets. But he has had several run-ins with the law since his career began, including a 2008 charge of of intimidation of a crime witness (eventually dismissed) and a 2013 arrest for battery. The flashy 26-year-old, nicknamed “The Problem” by his parents, has a record of 31-2, 23 by knockout, and won world championships in three weight classes by the time he was 23.

Broner is scheduled to defend his 140-pound world title against Ashley Theophane at the D.C. Armory on April 1, an event that now might be in jeopardy due to his legal issues. RingTV.com cited a source in the Cincinnati police department in reporting that District police are aware of the warrant for Broner’s arrest, but the website also reported a member of the boxer’s camp as saying “nothing has changed” regarding the upcoming fight.

On Thursday, Broner, who is reportedly currently training in D.C., posted a screenshot from his cellphone to his Instagram account, one that indicates plenty of confidence about his current situation. In it, Broner, who is associated with the phrase “About Billions,” responds to a query from ESPN boxing writer Dan Rafael about whether he will be able to make his scheduled fight in Washington.
