Boston Police report that officers who responded to a loud-music call at 541 Norfolk Ave. in Mattapan Thursday night arrested a Dorchester 16-year-old they say had "a machete sheathed in a black nylon case" down one pants leg.
Police say that when officers arrived at the three-decker shortly after 9:30 p.m., they found a major party underway in the backyard - there were guys out front frisking would-be guests and giving them hand stamps as they entered the backyard. That's not the sort of thing police normally see outside areas like the Theater District and Faneuil Hall, so officers moved in to break things up:
As the officers began to make contact with the homeowner, they simultaneously began to ask the gathered crowd to disperse. As this was happening, the officer’s attention was drawn to a 16-year-old male from Dorchester who appeared to be concealing an unknown object in his pants while he left the area on foot.
Perhaps realizing the extra long blade was hindering his departure, he discarded the sheathed machete, but was still unable to outrun officers, who charged him with being delinquent for carrying a dangerous weapon, police say. Police did not say if the teen had gotten the machete past the bouncers.
