A 20-year-old British streamer known online as Costakid, or Wolfi, was arrested in Miami and charged with aggravated assault with a deadly weapon, a third-degree felony under Florida law. Miami-Dade jail records set his bond at $5,000, and the arrest comes just days after a heated, widely shared video showed him in a confrontation with a man on South Beach.
The arrest was first reported by The Shade Borough, which noted that it remains unclear whether the South Beach confrontation seen in the video, which circulated Thursday, is connected to the charge now filed against him. No public authorities have confirmed the specific circumstances that led to the arrest, according to the outlet's reporting. Costakid, who hails from Suffolk, England, has built a substantial following through unpredictable in-real-life livestreams that frequently involve interactions and confrontations with members of the public, amassing a reported 500,000 followers combined across TikTok, Kick, and Instagram.
It's worth noting that an arrest or criminal charge does not mean a person has been found guilty, and Costakid has no publicly reported conviction connected to this charge. Still, the case lands him in serious legal territory. Under Florida Statute § 784.021, aggravated assault with a deadly weapon is defined as an assault committed with a deadly weapon without intent to kill, or with intent to commit a felony, and it carries a maximum penalty of up to five years in prison, five years of probation, and a $5,000 fine.
Why the Charge Could Threaten His Time in the U.S.
Beyond the criminal exposure, the felony charge could carry significant consequences for Costakid's ability to remain in the United States, and he may face broader immigration fallout tied to the case. The Eleventh Circuit Court of Appeals ruled in June 2026, in Senatus v. U.S. Attorney General, that Florida aggravated assault categorically qualifies as a crime of violence under federal law, classifying it as an aggravated felony for immigration purposes, according to the Law Office of Sabrina Damast.
That precedent matters because U.S. Department of State regulations already give federal authorities broad discretionary power to pursue prudential visa revocations against nonimmigrant visitors arrested on felony charges, even before any trial or conviction takes place, per the Hubbs Law Firm. Meanwhile, U.K. Foreign, Commonwealth & Development Office guidance makes clear that British consular officials can communicate with local authorities and notify relatives when a citizen is arrested abroad, but they cannot provide legal representation, post bail, or intervene in U.S. court proceedings, according to GOV.UK.
Who Prosecutes the Case Locally
Any formal prosecution stemming from the felony arrest would fall to the Office of the State Attorney for the 11th Judicial Circuit, led by State Attorney Katherine Fernandez Rundle, which handles felony cases arising from arrests across Miami-Dade County. Once defendants are released on bond in the county, re-offense is not uncommon: Miami-Dade's Pretrial Services Program releases thousands of qualified defendants each year, with roughly 8% to 9% re-arrested on new charges or failing to appear for court dates, according to the Miami-Dade Corrections and Rehabilitation Department's annual report.
Further details about what led to the charge are expected to emerge as the case moves forward, though as of now the specific circumstances tying the South Beach video to the arrest have not been publicly confirmed.
