CAMBRIDGE – Middlesex District Attorney Gerry Leone informed the public today that a twenty-year-old college student was ordered held without bail following a dangerousness hearing in connection with an incident in which she is alleged to have stabbed her ex-boyfriend multiple times. The incident occurred on the campus of MIT University where the victim is a student.

Anna Tang, a student at Wellesley College, was arrested on October 23 and arraigned that afternoon in Cambridge District Court on charges of armed assault with intent to murder and home invasion.
