After you are arrested for assault bodily injury, a case will be forwarded to a local district attorney’s office for review by a criminal prosecutor. Generally one of three things will happen:
Prosecutors will accept a case immediately upon intake;
Prosecutors will send the case back to police for additional information or investigation and then accept it at a later date; or
Prosecutors will reject it outright.
If a case is accepted for prosecution, you will be formally charged with assault bodily injury and required to make an appearance in court, be represented by counsel (or go pro se) and dispose of the case.
