A Detroit man is facing fresh federal charges after agents say they uncovered suspected fentanyl, multiple firearms, and even a flamethrower during a March raid on a west side apartment. A federal grand jury has indicted Brock Urian-Anthony Biffle, 40, on counts of possession with intent to distribute fentanyl, possession of a firearm in furtherance of a drug-trafficking crime, and being a felon in possession of a firearm. He is scheduled for federal arraignment on June 3, 2026.
What investigators say they found
According to investigators, the March 17 search of Biffle’s West Chicago apartment by ATF agents and the Detroit Police Gang Intelligence Unit turned up roughly 51.4 grams of suspected fentanyl, a KAK KF-15 5.56-caliber rifle, and a disassembled Glock 21 .45-caliber pistol with an extended magazine. Officers also reported seizing multiple rifle magazines and ammunition, 86 Suboxone films, a digital scale with suspected narcotics residue, $617 in cash, and a Pulsefire flamethrower with an attached fuel canister. The indictment reportedly includes forfeiture allegations tied to the drug and gun counts, per ClickOnDetroit.
How police say the case unfolded
Court records cited in local reporting say the case started the night of March 12, when officers watching the area of Joy and Stout reported seeing what they described as a "hand-to-hand transaction" involving a burgundy Dodge Ram later linked to Biffle. Police say the truck was later reported stolen, license-plate readers placed it near West Chicago and Evergreen, and surveillance footage showed a man moving the vehicle behind the apartment building. Officers then stopped a Nissan, with Biffle riding as a passenger, and arrested him. A field test on residue collected during that stop reportedly came back positive for fentanyl, per ClickOnDetroit.
Charges, criminal record and next steps
State records indicate Biffle’s criminal history dates back to at least 2004 and that he was placed on supervised release on April 28, 2025, under conditions that barred him from possessing firearms. Per the Michigan Department of Corrections, his record lists aliases including "Pride" and "Reggal Jackson" and details multiple tattoos also referenced in court filings. The 36th District Court record shows he appeared for a probable-cause hearing in late March, and federal prosecutors have since shifted the case to U.S. District Court in Detroit for arraignment, per the 36th District Court.
Why it matters
Fentanyl remains at the center of federal and local drug enforcement efforts in southeast Michigan, with the DEA Detroit Field Division reporting significant 2025 seizures of fentanyl and counterfeit pills as part of a stepped-up crackdown. That wider push helps explain why ATF agents and Detroit’s gang-intelligence officers are teaming up on cases that allegedly mix drug trafficking and illegal weapons in neighborhood apartments, according to the DEA’s seizure summary.
