BOSTON—In a dramatic late-night operation, officers assigned to District A-1 (Downtown) nabbed Mark Dioguardi, 37, of Revere, on serious drug trafficking charges. The arrest unfolded on October 20, 2025, around 10:30 p.m., when a vigilant officer spotted a suspicious man standing near 41 Bowdoin Street, fixated on his cell phone and glancing toward Cambridge Street.

When approached, Dioguardi made a beeline for the steps of a nearby private property at 13 Bowdoin Street, prompting officers to conduct a stop. Their instincts paid off—official police reports indicate they recovered a large plastic bag containing sixteen individually wrapped bags of fentanyl, weighing in at approximately 10 grams.

In addition to the drugs, officers seized $231 in cash, a digital scale, and drug packaging materials. Dioguardi was swiftly placed under arrest and is set to face a Boston Municipal Court judge on multiple charges: Trafficking of Class A substances, Possession with Intent to Distribute Class A (Subsequent Offense), and Possession of Class A.

Boston Police Department officials shared these images with the public.

This alarming bust highlights the ongoing struggle against opioid trafficking in the city, as fentanyl continues to pose a severe threat to local communities. With overdose deaths skyrocketing across Massachusetts, the swift action by downtown officers exemplifies the crucial front line effort in combating this epidemic.
