Two men and a woman were arrested earlier this week during a raid on a River Street apartment in which federal, state and local investigators found 100 pounds of fentanyl powder and pills, three industrial pill-press machines and numerous sealed Priority Mail envelopes containing pills that were ready to be dropped off at a local post office, the Suffolk County District Attorney's office reports.

Rahelin Reynoso, 33 and Quenty Ogando, 44, had bail set at $100,000 each at their arraignments Wednesday in Dorchester Municipal Court on charges of trafficking more than 200 grams of fentanyl, the DA's office reports. Erika Prado, 31, had bail set at $50,000.

According to the DA's office, Postal inspectors, Homeland Security agents, state troopers and BPD officers raised an apartment at 43 River St., near Old Morton Street.

The seized fentanyl has a street value of about $2.25 million, the DA's office says.
