The homeowner had rented out his residence on a short-term-rental platform. When the party got out of hand, he called BPD himself and asked them to remove the tenants and their guests. Officers from District B-3 arrived to find the crowd refusing to leave.

The three arrestees are Ryan White Jr., 20, of Randolph, Daktari Rose Deacon, 20, of Hyde Park, and Jaymier Teixeira, 19, of Taunton. None are Boston residents.

Officers found White in a third-floor bedroom, attempting to conceal a loaded pistol beneath a pillow. In an adjoining bathroom, Deacon emerged as officers arrived — and a second loaded firearm, this one fitted with an extended magazine, was recovered on the spot. A third loaded firearm was pulled from a closet in a second bedroom, wrapped up alongside a pile of cash.

Teixeira, who was not armed, was arrested for repeatedly refusing officers' lawful orders to leave.

White is charged with carrying a firearm without a license, carrying a loaded firearm, and possession of ammunition without an FID card. Deacon faces the same three counts plus possession of a large-capacity firearm. Teixeira faces disorderly conduct.

No injuries were reported. All three defendants are due in Dorchester District Court.
