ROXBURY (CBS) — A 15-year-old boy was arrested Wednesday morning after police say he fired a gun during a struggle in the lobby of the Boston School District headquarters building in Dudley Square.
Boston Police said the shooting took place around 9:20 a.m. at the Washington Street building, where students sign up for classes.
BPD Commissioner Bill Evans said the shooting arose from a confrontation between the 15-year-old and another child who was walking down from the second floor with his mother after registering for school. He said the two are believed to have known each other.
