Braintree Police report arresting an armed career criminal for last night's gunfire that ended with SWAT teams roaming a locked down South Shore Plaza.
Michael J. Spence Jr., 23, is charged with shooting his gun after running into an enemy in the Macy's shoe department around 7 p.m., police say.
Police say that with the help of Boston Police investigators, they were able to track Spence to Quincy, where they arrested him early this morning. At the scene, police had said the gunfire - which injured no one but led to a mall lockdown - was the result of interaction between rival Boston gang members.
Spence was charged with unlawful possession of a firearm, unlawful possession of ammunition and discharging a firearm within 500 feet of a building in use.
In 2014, Boston Police arrested Spence on a variety of gun charges in the Four Corners section of Dorchester. At the time, Spence, then 21, was already classified as "Armed Career Criminal Level 1," which meant he had been convicted of a violent crime.
