Understanding Aggravated Assault and Battery Charges in Massachusetts

In Massachusetts, Aggravated Assault and Battery is a more serious form of assault that typically involves specific aggravating factors, such as:

According to Massachusetts General Laws Chapter 265, Section 13A, the basic definition of assault and battery involves the intentional touching of another person without consent, which causes bodily harm or is offensive. When aggravating circumstances are present, the penalties can increase significantly.
