Another alleged major North Shore drug pusher is facing serious charges of distributing fentanyl, cocaine, and methamphetamine — and even shaking down one of his own dealers at gunpoint.

Federal law enforcement arrested Harvey “Big Opp” Rodriguez, 29, of Lynn, on Wednesday. He was charged in federal court in Boston with one count each of conspiracy to distribute controlled substances and conspiracy to interfere with commerce by robbery.

Rodriguez’s arrest comes following a lengthy investigation into the fertile drug and manufacturing operations north of Boston.

The investigation has already ensnared several of Rodriguez’s fellow alleged distributors, including Schuyler Oppenheimer of Cambridge, whose case is still pending; Vincent “Fatz” Caruso, who pleaded guilty to five counts and was sentenced to two decades in prison; and Caruso’s underling, Ernest “Yo Pesci” Johnson, who got seven years. All appear in court papers related to this case.

According to the criminal complaint, Rodriguez led the “criminal enterprise” known as “Big Opp Entertainment” or “Brothers Over Everything,” referred to in court papers as BOE.

His criminal history includes multiple arrests but no convictions. Still, FBI Special Agent Eric Poalino states in an affidavit that law enforcement considers him a known distributor of fentanyl, especially in pressed pill form, as well as methamphetamine and cocaine.

During the investigation, Poalino alleges, Rodriguez and his crew sold drugs at least four times to cooperating witnesses and carried out two shakedowns of his own dealers — one of which led to the robbery charge.

In that incident — which federal authorities refer to as a Hobbs Act robbery — Rodriguez was one level removed from the cocaine dealer he allegedly robbed at gunpoint. Although he wore a mask during their dealings, investigators pieced together that he was the distributor involved.

According to court papers, the dealer requested a kilogram of cocaine through a cooperating witness, who passed the request to Rodriguez. The deal was set for $24,000 in the dealer’s apartment.

When the dealer wanted more, a second deal was set up. But when the cooperating witness exited the apartment to supposedly retrieve the drugs, Rodriguez and another man “bum rushed” in with semiautomatic Glock pistols in hand and demanded the money without providing the goods.

The 70-page affidavit supporting the criminal complaint is filled with text messages that prosecutors say are between Rodriguez and his associates. The messages are short, expletive-ridden bursts of text-speak that make them difficult to quote.

At times, Rodriguez would instruct others to move the conversation to an encrypted platform: “Yo hit me thru Signal,” reads one message, referencing the secure messaging app.

According to the affidavit, investigators built their case through these text communications and surveillance footage placing Rodriguez at locations tied to his alleged activities.
