In a disturbing development from the world of combat sports, former UFC heavyweight contender Jairzinho "Bigi Boy" Rozenstruik has been arrested following a domestic violence incident involving his wife in Pembroke Pines, Florida. The arrest, which took place on January 19, 2026, has sent shockwaves through the mixed martial arts community and raised serious concerns about athlete conduct outside the octagon.
Details of the Violent Altercation
According to the official arrest report released by the Pembroke Pines Police Department, the physical altercation began while the couple was driving from a storage unit. The victim informed officers that an argument escalated after she ignored Rozenstruik, prompting the fighter to slap her hand and knock her cellphone to the floor. The situation took an even more violent turn when they arrived at a Bank of America location.
Escalation at Bank of America
The police report details that Rozenstruik allegedly grabbed his wife's arm to prevent her from exiting the vehicle. Their argument intensified further when the former champion attempted to kiss his wife. When she refused and called him a "nasty beast," he reportedly became enraged and bit her on her right bicep, leaving visible marks that were documented by authorities.
Further Confrontation at Club Fit Plaza
The couple later stopped at Club Fit Plaza, where Rozenstruik allegedly again prevented his wife from leaving the car. In what she described as an act of self-defense, the victim reportedly punched him in the face to escape the vehicle and seek help. This sequence of events paints a troubling picture of escalating domestic violence that required physical resistance to end.
Legal Consequences and Immigration Complications
The 37-year-old fighter was subsequently booked into the Broward County Main Jail on multiple charges, including a third-degree felony with bond set at $2,500 and a misdemeanor with bond set at $1,000. Due to his status as a Surinamese national, an immigration hold has been placed on him, which could complicate his release even if bail is posted. This additional layer of legal complexity adds significant hurdles to his potential release from custody.
Rozenstruik's Fighting Career and Initial Confusion
Jairzinho Rozenstruik was a longtime fixture in the UFC's heavyweight top 10, known for his elite kickboxing skills and devastating knockout power. His tenure with the premier mixed martial arts promotion ended in 2025, and at the time of his arrest, he was the reigning heavyweight champion for the Dirty Boxing promotion. Initially, some reports from Surinamese media suggested the arrest stemmed from a "neighbor dispute," but the official Florida police report specifically identifies the victim as his wife and classifies the charges as domestic violence.
Current Status and Lack of Response
As of now, the case remains pending trial, with no resolution in sight. Neither Rozenstruik nor his legal representatives have issued a formal statement regarding the specific allegations of the biting incident. The silence from his camp has left many questions unanswered about what transpired during that fateful January day and what might have led to such extreme behavior from a professional athlete.
The domestic violence allegations against Rozenstruik represent a serious fall from grace for a fighter who once competed at the highest levels of mixed martial arts. The detailed police report provides a chilling account of the events that led to his arrest, highlighting patterns of controlling behavior and physical violence that culminated in the biting incident. As the legal process unfolds, the combat sports world watches closely to see how this case will be resolved and what consequences Rozenstruik will face for his alleged actions.
