On Tuesday, September 16, 2025, officers assigned to District B-3 (Mattapan) arrested Ariannky Soto, 26, and Anyi Perez, 30, both of Dorchester, on multiple firearm and drug-related charges.
Around 1:00 AM, officers on patrol observed two individuals loitering in an alley next to 9 Charlotte Street. As officers approached, the two individuals quickly walked toward a nearby apartment building. One individual appeared to be reaching into his pocket and grabbing at his waistband, prompting further attention from the officers.
Police stopped the individual as he attempted to enter the building, while the other was detained near the side of the property. Responding officers soon located a firearm in the front yard of 15 Charlotte Street and all three individuals were handcuffed.
While one suspect was being placed in a cruiser for transport, officers noticed him manipulating an item in his hands. Upon removal from the vehicle on scene, officers observed a white powdery substance on the suspect’s hands.
District B-3 Detectives were called to the scene to assist in processing evidence. The recovered firearm was identified as a Beretta Pietro, loaded with seven rounds in the magazine.
Further investigation also revealed that two of the suspects had active arrest warrants.
Both suspects were taken into custody and are expected to be arraigned in Dorchester District Court on the following charges:
Soto:
- Carrying a Firearm without a License
- Carrying a Loaded Firearm without a License
- Possession of Ammunition without an FID Card
- Warrant: Various Motor Vehicle Law Violations
Perez:
