Good grief.

Transit Police arrested a woman from South Boston for allegedly spitting in the face of a disabled person and then physical assaulting the person in Harvard Square last Wednesday.

Joanna Drafahl, 20, has been charged with assault and battery on a disabled person.  Police posted a photo of the suspect on tpdnews411.com and asked for the public’s help in identifying the suspect which it ultimately did.
