Boston Police, in particular the department’s BPD Youth Violence Strike Force, were kept very busy over a 90-minute stretch on the Monday holiday dealing with two instances of firearms-related activity, one of which involved unruly crowd behavior

At about 4:30 p.m., members of the Strike Force arrested Donta Lewis, 28, of Boston, and Lamont Jacobs-Barrows, 21, of Walpole, on firearm related charges following an investigation in the area of Hemenway Park on Adams Street in Dorchester. As the officers approached to speak with the suspects, they immediately sprinted away on foot but were placed in custody following a pursuit. Officers then recovered a firearm that had been discarded by Lewis and two firearms that were discarded by Jacobs-Barrows as they fled. The suspects will appear in Dorchester District Court on firearm and ammunition related charges.

About 90 minutes later, around 6:15, Strike Force members arrested seven suspects while recovering seven firearms during an investigation in the area of 17 Elizabeth Street in Mattapan. As the officers approached the scene, an adult male fled on foot discarding a firearm into a parked motor vehicle along the way.

He was quickly subdued, but as the officers attempted to secure him for transport, a large and unruly crowd began to gather around the arresting officers. Citywide units were called to help secure the scene at which time six other firearms were located in the immediate area, leading to the arrest of three more adult male suspects on firearm- related charges. Three other adult male suspects at the site were placed in custody on charges of assault and battery on a police officer.

The BPD has not verified the identities of these suspects at this time.  All parties will appear in Dorchester District Court this week for arraignment.
