Former UFC heavyweight Jairzinho Rozenstruik, who went 2-0 for Dirty Boxing in 2025, is the latest combat sports athlete to land in trouble with the law.
Rozenstruik, 37, was arrested on Monday and hit with a pair of charges stemming from an altercation with a woman— domestic violence battery (touch or strike), and false imprisonment of person.
Cageside Press confirmed Rozenstruik’s arrest with Broward County, Florida officials following an initial report by MMA Junkie. Rozenstruik faced a relatively light bond of $3500 combined for the two charges, but was also placed on an immigration hold.
According the police records, Rozenstruik allegedly slapped a phone away from the unnamed complainant, attempted to kiss her, and bit her as part of an argument that took place inside a vehicle in Pembroke Pines, FL. When she attempted to exit the vehicle, Rozenstruik slapped her hand, and later took her to another location— leading to the false imprisonment charge.
Rozenstruik, who previously competed for both the UFC and RIZIN Fighting Federation after a stint in kickboxing, has not commented on the matter publicly. Originally from Suriname, “Bigi Boy” headlined six events for the UFC, and was ranked inside of the top 10 at heavyweight, though he never competed for the title. He was released by the promotion in February 2025 off a loss to Sergei Pavlovich.
